The “somatic” cells are different from the “gametes” in one specific way. What do somatic cells do that Gametes dont? A. Divide B. Get passed to offspring C.build the body D. Grow inflexible walls
Answer:
option B
Explanation:
Gametes are haploid because a sperm and an egg fuse during fertilization to create a new organism with diploid cells. Mutations in somatic cells can affect an individual organism, but they do not affect the offspring since they are not passed on during reproduction.

In the intrinsic pathway, the reaction begins with clotting factors from the _.
Answer:
Clotting factors are circulating in the blood.
Explanation:
In the intrinsic pathway, the body is responding intravascular damage through binding of platelets, exposure of chemicals or even collagen from endothelial membranes. The most of the clotting factors are synthesized by the liver and circulate around the blood stream until they are needed or until they are degraded based off their half lives.
When the platelets start to aggregate they release chemicals and have proteins that can attract the clotting factors. In the intrinsic pathway, clotting Factor XII starts off the cascade. Hope that helped :)

Consider the following DNA molecule: 5' TTC CAT GGA 3' 3' AAG GTA CCT 5' If this molecule were transcribed, what would be the resulting RNA molecule
Answer:
DNA strand: 5' TTC CAT GGA 3'
RNA strand: 3' AAG GUA CCU 5'
Explanation:
From the DNA template, an RNA molecule will be transcribed that is single stranded. So, it will read off the code from the 5' to 3' strand of DNA to create the RNA molecule made of complementary bases, in triplet codons. The enzyme that carries out this function is RNA polymerase.

What is the savanna hypothesis? Group of answer choices Bipedalism was selectively favored because it helped our ancestors to stay cool in their warm environment. Bipedalism evolved in early humans that were monogamous, specifically to allow male human fathers to provision food and resources to human female partners.
Answer:
Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.
Explanation:
The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.
The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.
In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.
The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.

4. In the background, the presence of naturally occurring enzymes in fruits and vegetables was discussed. Using your results from this exercise as a basis to guide your thoughts, do you think that cooked, frozen, or raw fruits and vegetables would contain the most active enzymes?
Answer:
The fruits inside do not have enzymes, but if our body when digesting them, if these fruits are cooked they are much easier to digest by our digestive enzymes and if they are raw, digestion will be more laborious since it will have to break more masses chemicals that were not destroyed by cooking.
Regarding freezing, it does not intervene in digestion.
Explanation:
The cooking of vegetables or fruits like meats generates that some chemical unions are destroyed, thus exposing the most internal structures in enzyme activity.
You are interested in studying if scalloped alleles follow the expected Mendelian inheritance patterns. What crosses will best allow you to study the inheritance pattern from a single generation and why?
Answer:
Reciprocal crosses
Explanation:
Reciprocal cross is crossing in all possible ways. Such that a parent used as a male can be further used as a female while the parents used as a female can be used as a male. This cross helps to show if indeed the inheritance follows the simple mendelian pattern of inheritance if not the inheritance is somewhat complex and an allele of the gene has more domineering power over the other when used as a specific parents.
The first cross will be between the parental genotypes to obtain the first filial generation offspring. This crosses will be done on both ways
Example
AA × bb
Where AA is the female and bb is the male
bb × AA
Here bb has been used as female while AA is used as a male
If the offspring of the two crosses are the same there is no reciprocal difference and the pattern of inheritance is mendelian fashion if they are different there is reciprocal differences.

Explanation:
If evolution is based upon there being genetic diversity between generations, how does the lack of genetic differences existing between daughter cells created via mitosis impact the theory of evolution
Answer:
See the answer below
Explanation:
If evolution is based upon genetic diversity, it means that evolution in organisms that only reproduce by mitotic division will depend largely on the frequency of random mutation of genes.
The only way that genetic diversity can occur between daughter cells formed from mitosis is if mutation takes place. Mutation general means a sudden change to the gene sequence of an organism.
Without mutation, evolution in mitotic organisms will be non-existence because there are no new genes or alleles being introduced into the gene pool.
Caffeine prolongs and intensifies the effects of epinephrine. Which of the following potential mechanisms of action of caffeine is consistent with this effect?
a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.
b. a competitive antagonist of cAMP binding to PKA.
c. stimulates phospholipase Cb.
d. inhibits sarcoplasmic/endoplasmic reticulum Ca 2 + - ATPase.
e. activates PKC.
Answer:
a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.
Explanation:
The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.

Which step of desalination must be done before water is condensed and collected?
Water is heated until it evaporates.
Water is frozen, so it becomes ice.
Water is transported from one area to another area that has little water.
Water is collected and salt is allowed to settle at the bottom.
Answer:
Water is transported from one area to another area that has little water. Water is collected and salt allowed to settle at the bottom.
Explanation:
Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.
Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.
Answer:
A. Water is heated until it evaporates.
Explanation:
Traditionally, the best way of taking salt out of water has been through vacuum distillation. The salt water is enclosed at a low pressure to reduce its boiling point, making it easier to vaporize to separate the salt from the water.
In Pennsylvania, wolves have been extinct for many years. They used to feed on white-tailed deer, but not that the wolves are gone, the population of white-tailed deer has exploded. This means that this community:______
a. Was under top down control
b. Was under bottom up control
c. Lacks a fundamental niche for wolves
d. Lacks a fundamental niche for deer
Answer:
The correct answer is a: The community was under top-down control
Explanation:
Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem. These systems are affected by the presence/absence of the superior predator influences all the lower links in the trophic chain.
In the exposed example wolves, that are considered to be the top predators, affected the white-tailed deer populations being the cause of its decrease. As wolves used to feed on white-tailed deer, they kept these populations under control, but once the wolves got extinct, the deer population increased again. Probably, this explosion in the deer´s population also affected its lower link in the trophic chain.
Stem cell transplants may someday be used to treat Parkinson's disease. Researchers are hopeful that these cells would alleviate the symptoms of Parkinson's disease by
Answer:
Researchers are hopeful that these cells would alleviate the symptoms of Parkinson's disease by secreting the neurotransmitter dopamine.
Explanation:
Dopamine is a neurotransmitter released by the brain that plays a role in pain processing at various levels of the central nervous system. This includes the spinal cord, periaduectal gray matter, the thalamus, the basal ganglia, the insular cortex, and the cingulate cortex. Low dopamine levels are associated with the painful symptoms that frequently occur in Parkinson's disease. Parkinson's is generated from a neurodegenerative disorder that mainly affects dopaminergic neurons, responsible for producing and secreting dopamine within the brain. When these neurons degenerate, dopamine levels decrease and the consequences are tremor, muscle stiffness and difficulty making voluntary movements, among others. In Parkinson's disease, there is a loss of dopaminergic neurons and a potential treatment would be that the lost neurons could somehow be replaced. One possibility is to transplant stem cells that differentiate into dopamine-producing nerve cells.
The central (Haversian) canal that runs through the core of each osteon is the site of ________. adipose tissue and nerve fibers cartilage and interstitial lamellae blood vessels yellow marrow and spicules
Answer:
Blood vessels and nerve fibers
Explanation:
The Haversian canal serves as the bone tissues and it runs through the core of each osteon. The osteon surrounds the Haversian canal and contain structures called lamellae.
These lamella are made largely of collagen fibers and also various network of rich blood vessels and cells which produces blood cells in the body. Nerve cells which helps in the relay of impulses are also present. The rich contents of the bone gives it its strength and durability.
Answer:
The correct answer is: blood vessels and nerve fibers.
Explanation:
Haversian Canals are a group of tubes that are located in the more peripheral region of the bone, known as the cortical bone. The cortical bone is hard and compact and is composed of several concentric layers of bone cells (osteocytes and osteoblasts) that circle around a haversian canal, which contains capillaries and nerve fibers. This structure is called an osteon.
Haversian Canals are very important for the correct functioning of the bone, as they give the cells their needed blood supply and innervation.
How did the death of chestnut tree result in the growth of the ecosystem
Answer:
add nutrients to the soil.
Explanation:
The death of chestnut tree result in the growth of the ecosystem because when the chestnut tree dies, the decomposers such as fungi and bacteria start feeding on the dead tree and as a result nitrogenous waste is produced mixed with soil which is the essential nutrient for the plants. These nitrogenous waste is used by the plants to make amino acids and as a result the growth of an ecosystem occurs.
