Answer:

All of the cells found in the blood come from bone marrow. They begin their life as stem cells, and they mature into three main types of cells— RBCs, WBCs, and platelets.

Answer:

True

Explanation:

The attached image shows a table that displays the eight (8) planets, their respective average distance from the sun and their respective orbital speeds.

The question only relates the orbital speed of planets Uranus and Venus, which is 7km/s and 35km/s respectively.

40% of the orbital speed of planet Venus is:

= 40/100 × 35

= 0.4 × 35

= 14

According to the table in the image, Uranus orbits around the sun at a speed of 7km/s, which is lesser than 40% of Venus's orbital speed (14km/s).

Therefore, it is TRUE that Uranus orbits the sun at less than 40% of the orbital speed of Venus.

Answer:

Tyrosine and phenylalanine are amino acids required for the synthesis of catecholamines

Explanation:

The catecholamines are hormones composed of a catechol ring group (benzene) and an amine lateral chain. One of the most common catecholamines is the neurotransmitter norepinephrine (noradrenaline). The biosynthesis pathway of the norepinephrine hormone includes the following steps: 1-tyrosine hydroxylase produces L-DOPA from tyrosine, 2-L-DOPA is subsequently tranformed into dopamine by the L-amino acid decarboxylase, and finally, 3-this chemical precursor is converted into norepinephrine by the action of the dopamine β-hydroxylase.  

Phenylketonuria is a congenital metabolic disease associated with a decrease in the metabolism of phenylalanine (Phe), which is an amino acid residue that acts as a precursor of different catecholamines including dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). Dietary restriction of tyrosine and phenylalanine is the most common treatment against phenylketonuria.

Answer:

(1) by increasing carbon dioxide and decreases oxygen

The destruction of the rainforests will affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen.

Rainforests, like the Amazon, are the world's greatest concentration of living trees. Through the process of photosynthesis, these trees contribute to the composition of the atmosphere that we enjoy every day and depend on to survive.

All trees perform photosynthesis, the fuel for this is carbon dioxide. This process then releases oxygen into the atmosphere as a by-product. For this reason, the destruction of the rainforests will affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen.

Answer:

Hello. I numbered your cells to make it easier to name them. The image with the numbers is attached.

cell 1: Interphase.

Cell 2: Telophase.

Cell 3: Metaphase.

Cell 4: Prophase

Cell 5: Interphase.

Cell 6: Anaphase.

Explanation:

In the interphase, it is possible to notice that the cell increased its volume, due to the increase in the size of the organelles and the increase in the number of the organelles, which indicates the beginning of the cell cycle.

Prophase is really the beginning of the cell cycle. At that moment, you can see that the nuclear membrane has been disorganized and we can see a 'tangle' of the cell interior that is very full and disorganized. This is mainly because the material present in the nucleol spreads through the cell.

In the metaphase, the chromosomes are condensed and start to connect to each other forming the spindle fibers, which are located right in the middle of the cell, forming the equatorial plate.

In anaphase there is a rupture of the centromeres and sister chromatids. Each part of these elements migrates to one of the poles of the cell. This is mainly due to the shortening of the spindle fibers.

Telophase is the final phase of the cell cycle, at that moment, the spindle fibers disappear, the chromosomes are condensed and the nuclear membrane is reconstructed. However, the cell has not yet separated and it is possible to see two nuclei in a single cell, each nucleus is at a pole, indicating that the division will occur.

Answer:

The egg is made by the hen. It creates an embryo (the future chick, the little white spot that you see on the egg yolk) which will be fed by the yolk of the egg.

The yolk is a food reserve (called the yolk) for the chick in formation: by eating the yolk, the embryo becomes a chick.

The white consists of gelatinous proteins, which the future chick will eat during incubation, warm for 21 days under the hen.

The shell protects the embryo, the yolk and the white. It is made of two membranes that are made from calcium that the hen stores in her bones and intestines. In the chicken's belly, muscles spin the egg during training and give it its perfect shape.

The shell is made in such a way that it is difficult to the pan from the outside, but very easy to break it from the inside. So the hen does not crush her eggs when she is brooding, but the chick can come out easily!

It works pretty much the same for all birds, reptiles, fish ... that lay eggs. On them, moreover, oviparous animals.

The right answer is D.

Breathing is the process by which oxygen from the air gets into your lungs and gets into your body. Our lungs take oxygen from the air and carry it into our bloodstream, which carries it to the cells, tissues and organs that allow us to walk, talk and move.

Our lungs also remove carbon dioxide from our blood, through the air we breathe.

Answer:

Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).

The two great arms of this immunity are the humoral and the cellular.

The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.

Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.

It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.

Explanation:

Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.

Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte

Answer

The places where the fertilized egg got implanted are not appropriate

for the fetus´ development. These places lack space and needed tissues.  

Explanation:

Ectopic pregnancies occur most often in the Fallopian tubes,  which are the structures that transport the eggs from the ovaries to the uterus. But some other times, ectopic pregnancies might also occur in ovaries, abdominal cavity, or in the cervix.

These pregnancies are not viable, this means that the fertilized egg can not survive. However, the firsts stages of its development seem to be normal and involve an increase in tissues surrounding the egg.

As the places where the egg got implanted are not prepared for its development, they might be harmed. These areas do not have enough space,  nor nutritional tissues needed by the embryo. And as the fetus grows, it creates a constant pressure in the organ, that can make it burst. This provokes important bleeding that might cause the patient´s death if they are not properly assisted.    

At first, the woman might feel the normal symptoms of pregnancy, like the lack of the period during the firsts months or breast sensitivity.  But as the egg grows in the inappropriate place, there appear some new signs and symptoms, such as a light bleeding or pelvic pain. If the organ bursts, the bleeding might be so intense that the woman might be in danger.    

Answer:

Bleeding would occur because the baby is growing near the vaginal canal, which leads to the outside of the body. The cervix is the bottom portion of the uterus, so if the uterus is damaged, the entire uterus may need to be removed.
