The number of possible genetically different gametes for an organism equals
2N, where Nis the number of pairs of chromosomes. If an organism has four
pairs of chromosomes, how many different gametes can it produce?
O A. 16
O B. 4
O C. 8
O D. 32
Answer: it’s 16
Explanation: i took the quiz
If an organism has four pairs of chromosomes, 16 gametes can it produce. So, the correct option is A.
What are Gametes?A gamete is defined as the reproductive cell of an animal or plant while the female gamete is called the ova or egg cell, and the male gamete is called the sperm in the animal cells. Ova and sperm are haploid cells with each cell containing only one copy of each chromosome. During fertilization a sperm unite with the ovum to form a new diploid organism.
When the organism has four pairs of chromosomes, 16 gametes can it produce. In seed plants, the pollen is called the male sperm that produces the gametophyte while the female gametes are contained within the ovary of the plant.
So, the correct option is A.

What processes occur during G2 phase? Choose all which apply.
Cells do their normal work
Cells assess DNA replication
Cells duplicate their DNA
Cells synthesize proteins necessary for division
Cells divide their DNA into two nuclei
Explanation:
the last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

They are special in that they have a cellulose and hemicellulose-based cell wall that offers structural support and defence. Chloroplasts, specialized organelles found only in plant cells, perform photosynthesis to create molecules full of energy that the plant can use as food.
In contrast to plant cells, which have a cell wall, animal cells are often rounder in shape. They have a flexible cell membrane that controls how things enter and exit the cell. The nucleus, which houses genetic material, and the mitochondria, which power cellular respiration, are among the many organelles found in animal cells.

A paleontologist identified two distinct species of mollusks in the fossil record of a region. In the layer below a mass extinction that devastated the region, the paleontologist observed that shells of species A was present in small numbers over a widespread area whereas species B was abundant and found in a few restricted areas. Which of the following predictions about the fossil record in the layer above the mass extinction is the MOST likely to be supported by further excavations?
a. Species A survived because of its widespread range including some areas that were not as affected by mass extinction.
b. Species A survived because the low number of individuals meant that there was less competition for resources.
c. Species B survived because it was the more abundant and more individuals survived.
d. Species B survived because the population was concentrated in a few areas and had a higher chance of survival.
Answer:
a. Species A survived because of its widespread range including some areas that were not as affected by mass extinction.
Explanation:
The species distribution might confer extinction resistance during massive extinction events. One of the most important reasons for a species -or any other taxonomic group- to survive massive extinction is its wide distribution area.
The broad geographical range of a group -as Species A in the example- enhances the survival chances during mass extinctions. When the event occurs, it severely affects most individuals of a certain area. If the species is restricted to that area, then the species will probably disappear, no matter the number of individuals living there.
But if the species is widely distributed, there are more survival chances. The extinction event will only affect a few regions, but not all of them, meaning that some of the individuals of the species will be able to survive.
Probably as only a few individuals of species A got to survive, they must have suffered the effects of genetic drift after the disaster, causing a reduction in genetic variability.

UULUU 15 is Quritall Streptobacteria null hypothesis Scientic Method - An exemple: In early 2000 a disease appeared in the northeastern United States that had never been seen before. The disease produced a fever and nasal congestion causing the tip of the nose to turn red. The bacteria that caused the disease was isolated and found to be a certain type of streptobacteria. A certain antibiotic called Curitall has been effective against other similar streptobacteria, and so an experiment was set up to test it Curitall would be effective against this certain type of bacteria. On this discussion thread post what the null hypothesis is, and explain what would happen to people infected with this Streptobacteria if they don't take any antibiotic. For maximum points, compare expected rates of healing between experimental and control group subjects if Curitall does not work. Respond to instructors comments and questions as necessary,

During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.
Answer and explanation:
Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.
These hormones have many functions and they all work together to prepare the individual for a fight or flight response - like increasing heart rate and producing bronchodilatation. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.
When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.
AUGGCGUUU which of the following DNA strands could have been the template for this RNA?
Answer:
3' TACCGCAAA 5'
Explanation:
Transcription is the process by which a particular DNA sequence (e.g., a gene) is used as a template to synthesize a complementary RNA sequence that grows in a 5′ → 3′ direction. This RNA molecule is usually a messenger RNA (mRNA) which is then used to synthesize a polypeptide chain (i.e., a protein) by a process called translation. The complementary RNA molecule produced during transcription is synthesized according to the base pair rules, i.e., Adenine (A) bases always pair with Thymine (T) bases, while Guanine (G) bases always pairs with Cytosine (C) bases. In RNA, Uracil (U) bases pair with adenine, thereby replacing thymines during transcription.

Which statement describes a relationship that is an example of mutualism?
A. Remoras attach to and eat food on a sea turtle.
B. Ticks live on and drink blood from livestock.
C. Bees drink nectar from and pollinate flowering plants.
D. Rabbits live in and eat vegetables from garden plants.
Answer:
C. Bees drink nectar from and pollinate flowering plants.
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
In Ecology, mutualism can be defined as an symbiotic relationship or interaction between two or more living organisms of different species that typically involves each organism benefiting positively. Therefore, mutualism influences the survival and reproduction of living organisms in their habitats.
Hence, the statement which describes a relationship that is an example of mutualism is bees drink nectar from and pollinate flowering plants. The flowering plants serve as a source of nectar for bees to feed on while the bees engage in the pollination of the flowering plants, suggesting a mutual benefit (mutualism) between the two species.
Pollination can be defined as a process which typically involves the transfer of a pollen grain from the male part (anther) of a plant to a ovule, stigma, or flower of a female plant, in order to stimulate fertilization and production of seeds. Also, this transfer of a pollen grain (male gametophyte) is often effected by bats, wind, birds and insects such as bees.
