Answer:
If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.
Explanation:
As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.

What trait are narcissists likely to have that is associated with leader emergence but not effectiveness
Answer:
Agreeableness.
Explanation:
Agreeableness is the trait that narcissists likely to have which is negatively corelated and is associated with leader emergence but not effectiveness. The tendency toward self-interest would attract the person into follow his or her own goals rather than the interests of their group or company. The term Narcissism originated from Greek mythology, where a young man whose name is Narcissus fell in love with his own image reflected in a pool of water so that's why selfness and self interests refers to Narcissism.
130 and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14c?
A. 6 electrons, 7 protons, and 6 neutrons.
The correct answer is C. 6 electrons, 6 protons, and 8 neutrons.
Explanation
An isotope is a type of atom that is characterized by having a nucleus with a different number of neutrons. Additionally, isotope atoms are those that have the same number of protons in the nucleus (in the case of carbon 6 protons), but different mass numbers. In the case of the isotope of carbon, it has 8 neutrons (2 more neutrons than the regular carbon) and 6 protons in the nucleus, that is, that its mass is 14 (6 protons + 8 neutrons equals 14). According to the above, the correct answer is C.

You isolate a variant of the Hfr parent in question 6 that only shows recombination of the his+ and trp+ genes. The cross was ( HFR lac+, gal+, trp+, his+, strr X F- lac-, gal-, trp-, his-, strs ). This strain most likely:_________.
a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given
Answer:
The correct answer is - b. has become F-.
Explanation:
In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.
Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain his+ trp+.

Which of the following is correctly defined?
A. Ecosystem - A group of conspecific organisms.
B. Population - An individual life form.
C. Community - A group of populations.
D. Population - A group of communities.
I need help!!1
Answer:
both b and c I think..........
Population - An individual life form. and Community - A group of populations.
What is population?A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait.
A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common.
A statistically significant portion of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, or standard error, of a statistical study of a sample from the full population must be disclosed.
Therefore, Population - An individual life form. and Community - A group of populations.

Explanation:
purple flowers and round seeds could be both PPRR and PpRr because it's both dominant traits and heterozygous genotypes still show the phenotype of the dominant gene. purple flower and wrinkled seeds would be PPrr or Pprr for the same reason. white flowers and round seeds would be ppRR or ppRr, and finally white flowers and wrinkled seeds would be pprr. hope this helped :)
In most unsaturated fatty acids found in animal fats, vegetable oils, and biological membranes, the cis isomer predominates. true false
Answer:
The correct answer is - true.
Explanation:
Most unsaturated fats are oils and normally are biological membranes or plant-based such as vegetables. These fats mostly have cis isomer in them. Unsaturated fats help to lower blood cholesterol levels.
However, few oils show saturated fats but these are few in number, the majority are made up of unsaturated fats that have double bonds.
When body temperature increases, thermoreceptors are stimulated and send nerve signals to the CNS. The CNS sends motor signals to sweat glands, which attempt to reduce body temperature. This is an example of a __________ reflex.a. organ.b. stretch.c. withdrawal.d. visceral.
Answer:
d. visceral.
Explanation:
The visceral reflex is one that happens autonomously in the body, aiming to maintain the balance of the body through quick responses to some specific impulses. An example of a visceral reflex is the reduction in body temperature with the release of sweat from the sweat glands.
The visceral reflexes are controlled by the autonomic nervous system, using the sympathetic and parasympathetic nervous system.

To determine the location of an epicenter
Explanation:
A seismogram is a graph output by a seismograph ; a record of the shaking and vibration of the ground. By studying seismograms, scientists learn a lot about Earth's internal structure, like how fast the waves are moving and what type of material the waves are passing through.
5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.

What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae
Answer:
RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.
Dark skin ( a result of increased melanin production in equatorial populations), is likely a response to ultraviolet radiation because UV radiation causes:
Answer: Skin cancer
Explanation:
Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms. When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found) of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. This results in a tumor, which is the uncontrolled growth of cells (in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.

If the entire mRNA sequence for a polypeptide was AUGUACUCGCGACCGUAA, how many amino acids does the polypeptide have
Answer:
5 amino acids
Explanation:
The process of translation involves synthesizing a sequence of amino acids from a mRNA template. The mRNA molecule is read in a group of three nucleotides called CODONS. A codon specifies or codes for an amino acid.
In the question, a mRNA sequence was given as follows: AUGUACUCGCGACCGUAA. From this sequence comprising of 6 codons, 5 possible amino acids will be contained in the polypeptide encoded by this mRNA molecule as the last codon (UAA) is a STOP codon. The following are the codons in the mRNA sequence and their respective amino acids:
*AUG- methionine (met)
*UAC - tyrosine (Tyr)
*UCG - Serine (Ser)
*CGA - Arginine (Arg)
*CCG - Proline (Pro)
*UAA - Stop

is it possible that after the first meeting of male and female through sexual inter course
the female become pregnant after the sex??
Answer:
Yes, it is possible because, if the sperm from the male goes into the egg of the female it can cause the female to get pregnant by that male. And its very rare for the female not to get pregnant after having inter course with the male. That's only if they had unprotected sex.
