Carbohydrates is a body fuel that act as the major energy source in the body. It gives and provide energy in the body needed for biological activities.
In plants, carbohydrates make up part of the cellulose, giving plants strength and structure. carbohydrates is to form a structure called the glycocalyx.
Which sequence correctly represents the order of events during egg formation?
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.

Describe the biosynthetic pathway that produces catecholamines such as norepinephrine and epinephrine from amino acid precursors and explain how the lack of available amino acids precursors would impact homeostasis regulated by catecholamines.
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.

Cervical pregnancies are extremely rare. Women undergoing cervical pregnancies often experience unusual vaginal bleeding. In extreme cases, they may require a hysterectomy (removal of the uterus). Why do you think the symptoms and risk occurs with this type of ectopic pregnancy?
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.

2. If a nucleus has 8 chromosomes, how many chromosomes will be present after Telophase I? 3. What advantage does crossing-over have in reproduction? 6. Compare and contrast spermatogenesis and oogenesis (where do they occur, how many gametes are formed, when do they develop, etc):
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.
Since viruses are typically 20-200nm in diameter.. what is the best microscope to view them?
Answer:
electron microscope
Explanation:
Due to their extremely small size, the best microscope to view viruses would be the electron microscope.
The electron microscope has the capability to create resolved images of extremely small objects by utilizing electrons as a source of light instead of the visible light photon that is typical of light microscopes.
There are different two types of electron microscopes:
the scanning electron microscope, andthe transmission electron microscope.A typical scanning electron microscope creates an image of an object by detecting knock-off electrons from the object, whereas a transmission electron microscope uses electrons that pass through the object to create the image of the object.

I'm confused on labelling the stages of mitosis in these onion cells. I know what these stages look like illustrated in the textbook, but am confused when looking at actual slides of cells. Can anyone help? Photo is attached.
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.

Fast reproduction by binary fission enables bacteria to
cause infections in other organisms.
quickly modify their DNA to changing conditions.
change shape from coccus to bacillus.
transfer DNA from one cell to another.
Answer:
A.) Cause infections in other organisms
Explanation:
Binary fission helps the bacteria to cause infections in other organisms because of duplication of its genetic material.
Through fast reproduction in bacteria enables to cause infections in other organisms by binary fission.
How does binary fission help bacteria reproduce quickly?
During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells.
The two daughter cells are just like the parent cell. Binary fission can happen very rapidly.
In the process of binary fission, an organism duplicates its genetic material, or desoxyribonucleic acid (DNA), then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Many prokaryotic organisms like bacteria reproduce by the method of binary fission.
Therefore, the correct option is A that bacteria cause infections in other organisms.

what is a type of emigration where offspring move
away from their parents.
Answer:Dispersal
Explanation: This refers to offspring moving away from their parents. This prevents the offspring from competing with the parents for resources such as light or water. For example, dandelion seeds have “parachutes.” They allow the wind to carry the seeds far from the parents
1. One important feature of DNA is that it can be accurately copied and inherited from one generation to the next. Imagine if DNA was NOT accurately replicated. What errors could occur and how would they affect the offspring in the next generation
Answer:
Explanation:
If DNA is not accurately replicated it can lead to mutation. Mutation is a genetic disorder that occur when a change occur and affect the genome of an organism. It can be result in frameshift mutation shifting nucleotide arrangement.
When DNA is not accurately replicated, it could lead to formation of an entirely new protein different from the original which has a different function this could lead to a form of disorder in the offspring. The effect of this disorder depends on it severity.
Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen
by increasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and decreasing oxygen
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.

Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rate of 15 per 1,000/yr, and an emigration rate of 8 per 1,000/yr. What is the population growth rate
Answer:
0.023%
Explanation:
The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula
[tex]N/t[/tex] where N is the total change in the population size, and t is time.
When immigration and emigration are factored in, we now have the formula;
[tex](CBR +I) - (CDR + I)/1000[/tex]
[tex]= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\[/tex]
A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with balls stacked near its bottom. How is energy related to the change of state represented by the model? Atoms gain energy as a gas changes to a solid. Atoms gain energy as a gas changes to a liquid. Atoms lose energy as a gas changes to a solid. Atoms lose energy as a gas changes to a liquid.
Answer:
C. Atoms lose energy as a gas changes to a solid.
Explanation:
Physical changes of matter take place by adding or removing energy from the matter.
In the given images, The left cylindrical is showing gas phase while the right cylindrical is showing a solid phase.
The process of conversion of gas into solid is called deposition. Deposition process takes place when atoms lose their energy and have high kinetic energy so they directly convert into solid and not into liquid.
