Both daughter cells are stem cells at this point and are smaller than the parent cell C. Both daughter cells become specialized cells, they stop being smaller than the parent cell D. One daughter cell is a stem cell, one is a specialized tissue cell, both are smaller than the parent cell

Answers

Answer:

B. Both daughter cells are stem cells at this point and are smaller than the parent cell.

Explanation:

The embryo passes through several consecutive cell divisions. With each division, the daughter cells become smaller in relation to their mother cells. In addition, these cells are embryonic and can be called pluripotent. This is because they have the ability to transform into any type of cell that the human body needs, including tissue cells.

Which is the correct sequence of events when the RER delivers transport vesicles to the Golgi apparatus? 1 – Small vesicles move material from one cisterna to the next. 2 – Enzymatic modification occurs. 3 – Arrival at the trans face. 4 – Arrival at a cisterna known as the cis face."

Answers

Answer:

The correct order of events when RER delivers transport vessicles to the Golgi apparatus are;

4,2,1,3

Arrival at a cisterna known as the cis face."

Enzymatic modification occurs.

Small vesicles move material from one cisterna to the next.

Arrival at the trans face.

Explanation:

Rough endoplasmic recticulum are flat sacs in the cytoplasm that help in the synthesis of protein. It vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed. The Golgi apparatus is an organelles in the cytoplasm that help to package protein into membrane bound organelle in the vessicles.

The vessicles that bud off join to the rough endoplasmic recticulum, Molecules travel through the Golgi apparatus through the vesicle transport till they get to the end of the assembly line at the biggest sacs from endoplasmic recticulum called the trans-Golgi.

Firstly, the particles arrive at cisterna known s Cis face. The cis face is the end of the organelle where substances enter from the endoplasmic reticulum for processing into the Golgi apparatus.

Then there is enzymatic modifications which is done by the activities of enzymes.

Small vessicles then Transport material from the cisterna.

It is then transported to the trans face. The trans face is where the particles leave in the form of smaller detached vesicles.

Explain the basic steps in the first half of photosynthesis. Describe the movement of electrons and the importance of hydrogen ions in developing a proton gradient that allows for ATP production.

Answers

Answer:

This simply refers to photolysis of water.

Explanation

Generally,two steps are involved in photosynthesis.

The light  dependent stage or light reaction,(which is the first part of photosynthesis,

The light independent stage (which is the second part.)

The light independent reactions involved the trapping of sunlight by the photo systems, in the leaves,and the splitting of the water molecules by sunlight.

          H20 + Sunlight → 1/2H+ +2 e- +1/2 O2.

The  movement of electron can be cyclic or non cyclic photophosphorylation, In Cyclic, photo system 1 absorbs  the electrons and pass these to the primary pigments in the leaves. This excited the electron  in chlorophyll molecule to higher energy levels , The electron emitted from the leaves is by a process called by photoactivation The emitted electron do not return to the photosystems,rather they are pick up by the primary electron acceptors  and returned to the chlorophyll molecules by electron carriers,NADP.

During this process Energy is released for ATPase synthase of  ATP for phosphorylation of ADP with phosphate,

In Non-cyclic photophorylation,photosystem I and II  absorbs the electrons as Z-scheme  movement of electrons.,Photoactivation  of chlorophyll takes place as in the Cyclic.The primary electron acceptors  takes the  excited electrons  to move along the chain of electron carriers.This makes the photosystems positively charged.

Hence to regain stability the primary pigment of photo system 1 takes electrons from photosystem II.To replace its lost electrons, P II takes electrons from the photolysis of water.ATP is generated  as the carriers molecules transport electrons from the energy produced.

The hydrogen ions is used for the production of electrochemical gradients,which supplies the energy used by the ATPase synthase for the ATPs production.The process is called chemiosmosis. It  involved the  transports of H atoms by NADPH into the stroma,and the splitting of these into protons and electrons,The electrons  form ETC,which forms the PMF.The latter  pumped protons  into the thylakoid membrane,and as this returns it  generate the electrochemical gradient.

The ATP is used in the Calvin Cycle for CHO,proteins productions,

Answers

Hello. This question is incomplete. The full question is:

Study the diagram of the geologic time scale. Which method is most likely used to identify what happened before the start of the Paleozoic era?

a. Scientists study fossils from the Jurassic period.

b. Scientists observe index fossil records of the Mesozoic era.

c. Scientists examine fossil evidence during the Precambrian time.

d. Scientists explore the emergence of mammals and humans in the Cenozoic era.

Answer:

c. Scientists examine fossil evidence during the Precambrian time.

Explanation:

As you may already know, to facilitate the study of the geological periods of the earth, scientists, especially geologists, decided that the history of the earth should be buried in eras, periods and geological periods, so that the studies could be done in more specific and organized way.

The geological era before the Paleozoic era is the Precambrian period. During this period, there were forms of life on earth that generated fossils that allow scientists to record, date and understand this period, in addition to being able to relate it to others. Thus, the method most likely used to identify what happened before the beginning of the Paleozoic era would be to examine fossil evidence during the Precambrian period.

Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solution of sugar. Membrane A was immersed in 0.5% sugar solution, Membrane B was immersed in 1% sugar solution and Membrane c was immersed in 2% sugar solution. Predict the behavior of the three membranes?

Answers

Answer:

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

C. Cellular transport in which the cell membrane pinches around a substance in order to bring it into the cell.
D. Cellular transport in which substances move from areas of low concentration to areas of higher concentration.

Answers

Answer:

d

Explanation:

passive transport needs no energy W when transporting from high to low and need energy when transporting from low to high

Cellular transport that does not require cellular energy is the example of passive transport. The correct option is B.

What is passive transport?

Passive transport is a type of membrane transport in which substances are moved across cell membranes without the use of energy.

Differing from active transport, the one that uses cellular energy to move substances across cell membranes, passive transport utilizes the second law of thermodynamics to move substances across cell membranes.

Passive transport processes play critical roles in homeostasis. They maintain normal conditions within the cell and the organism as a whole by allowing substances to move into and out of the cell.

Active transport is defined as the movement of a solute from one side of the cell membrane with a low electrochemical potential to the opposite side with a higher electrochemical potential.

Thus, the correct option is B.

Read the text: Trans fat is obtained industrially after certain vegetable oils, under certain conditions, are hydrogenated and transformed into solid fat. This type of fat has been used in the production of some food products, such as stuffed cookies, giving them, for example, a more crunchy consistency. However, it is admitted that the excessive consumption of trans fat contributes to obesity and the development of cardiovascular diseases. a) What group of lipids do oils and fats belong to? b) How can we differentiate oils from fats at room temperatures, around 20 ° C? c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases.

Answers

Answer and Explanation:

a) What group of lipids do oils and fats belong to? Lipids and fats belong to the triglyceride group. Triglycerides are a mixture of glyceride esters and fatty acids. They are stored in specialized adipose cells, known as adipocytes. Adipocytes give a place to the adipose tissue in the organism.  

b) How can we differentiate oils from fats at room temperatures, around 20 ° C? At room temperature, fats can be recognized for being solid, while oil is liquid.

c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? The plant´s embryo needs to nurture while it is developing. The oil in the seeds plays the role of nutritive storage, together with other nutritive substances. These are used by the plant until it is able to photosynthesize.

d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? The advantage of the fatty layer under the skin is to keep or maintain the animal´s temperature. It is very common to find a thick fatty layer under the skin of animals that live in very cold environments, such as polar bears or deep divers marine mammals.

e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases. Cholesterol is a fatty substance needed for the good functioning of the organism. It is part of cellular layers and it plays a role in hormone synthesis and biliary salts. Although in excess they might be harmful as they tend to accumulate in the artery´s walls, blocking the passage of blood. This can lead to a heart attack.

Which of the following is TRUE regarding the flow of blood through the heart:__________
a) The pulmonary artery carries deoxygenated blood.
b) The aorta is responsible for carrying oxygenated blood to the pulmonary system.
c) During systole, blood is going from the atria to the ventricles by gravity.
d) During diastole, blood is flowing over the semilunar valves

Answers

Answer:

a The pulmonary artery carries deoxygenated blood.

Explanation:

This is the the only artery that transports deoxygented blood in mammals. specifically it carry deoxgenated blood from the the atria  to the pulmonary circulation. That is to the lungs  for the exchange of the C02 in the deoxygenated blood with oxygen  in the lungs.

The  blood thus become oxygenated,and therefore return through the pulmonary veins to the left ventricle.

From the left ventricle ,through ventricular systole,blood is empty into the aorta through the aortic valves into the  systemic circulation.

Although,they carry blood away from the heart,but the blood is de oxygenated instead of the usual oxygenated by arteries,They are still regarded as arteries  because of convey of blood away from the heart,a typical role of arteries

Answers

Answer:

Corn oil has a density of 0.7 g/cm3. Water has a density of 1.0 g/cm3. A piece of plastic with a density of 0.9 g/cm3 will sink in corn oil and float to the top of the water.

Explanation:

Density is a unit that let us know the quantity of mass that a substance has per unit of volume. In a solution, the component with lower density will float, and be on the surface.

If we compare the densities of corn oil and a piece of plastic, the plastic will sink because its density ( 0.9 g/cm³ )is higher than the one of the corn oil (0.7 g/cm³).

In the case of the water, the plastic will float to the top because its density ( 0.9 g/cm³) is lower than the one of water (1.0 g/cm³).

This theory is reinforced by the following facts:

Mitochondria and chloroplasts have some genetic information of their own, which would support their original independence.Both the mitochondria and the chloroplast have their own circular double-stranded DNA freely inside them, independent of the nuclear one. They behave like a bacterium, because they synthesize their own proteins, use 70s ribosomes (and not 80s ribosomes like eukaryotes), perform their functions through the membrane and replicate their DNA and perform binary fission to divide.
