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.

Which of the following choices is an example of a non-specific barrier?
skin
white blood cells
lymphatic system
the immune system
An example of a non-specific barrier is the skin. Thus, the correct option is A.
What are non-specific barrier?Non-specific barriers are the innate, or nonspecific type of immunity of the defense system with which a person is born with. Non-specific barrier protects a person against all the antigens. Innate immunity involves the barriers which keep the harmful materials from entering the body. These barriers form the first line of defense in the immune response of an individual.
Nonspecific defense mechanisms include the skin, mucous membranes, secretions, excretions, enzymes, inflammatory responses, genetic factors, and the behavior patterns.
Skin is a physical and non-specific barrier which is covered with oily and acidic pH which ranges from 3 to 5, and the secretions from sebaceous and sweat glands, respectively.
Therefore, the correct option is A.

The endocrine system consists of ________
A)
association areas.
B)
neural networks.
C)
interneurons.
D)
glands.
Answer: The endocrine system consists of Glands.
The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.Some species of algae grow on fungi.

n a simple food chain, wolves eat deer and deer eat shrubs. A pack of wolves has a total biomass of 1,000 kilograms. Approximately what biomass of shrubs must have been eaten by deer to support that wolf pack, assuming that only shrubs, deer, and wolves exist in the food chain
Answer: 100000 kg of biomass of shrubs must be eaten by deer.
Explanation:
According to the Lindeman 10% law :
When energy is transferred from one tropic level to another successive tropic level, only 10% of the energy gets transferred while the remaining is lost in the environment.
We are given:
Biomass of the pack of wolves = 1000 kg
This means that 10% of the biomass of deer is 1000 kg
Biomass of deer will be:
[tex]10=\frac{1000}{x}\times 100\\\\x=\frac{1000\times 100}{10}=10000kg[/tex]
Now, this biomass of deer is 10% of shrubs' biomass.
This means that 10% of the biomass of shrubs is 10000 kg
Biomass of shrubs will be:
[tex]10=\frac{10000}{y}\times 100\\\\y=\frac{10000\times 100}{10}=100000kg[/tex]
Hence, 100000 kg of biomass of shrubs must be eaten by deer.

Will give Brainlyiest please hurry
Answer:
Genetic variation among plant populations often occurs along different climatic gradients, such as temperature and precipitation gradients.
Environmental factors are often responsible for the patterns of genetic structure observed at small spatial scales (Sacks, Brown, & Ernest, 2004).
During a scene in Gattaca, Vincent’s parents visited a doctor to select for the best traits for his future brother. They hoped that his brother would have the best possible chances for a successful life. Some of the traits mentioned in GATTACA included intelligence, height and any possibility of inheritable diseases. If you decide to have a child one day and are given the opportunity to select for special traits, would you do so? EXPLAIN Why or why not?

up over time.
C. Water near the shore of a lake becomes warmer on a sunny day.
O D. Water at the top of pan becomes warmer as water from the
bottom of the pan rises.
SUBMIT
Answer:
A
Explanation:
Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.

As humans grow, their bodies change.” Which statement best explains how humans grow?
Answer: Cells undergo cell division
Explanation:
"As humans grow, their bodies change.” The statement that best explains how humans grow is that cells undergo cell division.
When cells divide, thus brings about the making of new cells. This is referred to as cell division or cell reproduction. In this case, a single cell divides and then brings about two cells, then these two cells later make four cells .... This is unique and vital for every living organisms.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
