if a typical somatic cell has 12 chromosomes, how many chromatids and dna molecules are expected in each cell of that organism?

A person's immune system reacts against the viral protein after receiving the vaccine. Later, when the individual comes into touch with the actual virus, the immune system recognizes the virus protein and is ready to destroy the virus, protecting the person against Ebola virus sickness.

The Ebola virus disease (EVD) is a rare and fatal illness that affects both humans and nonhuman primates. Sub-Saharan Africa is home to the majority of the viruses that cause EVD. Direct contact with an infected animal (such as a bat or nonhuman primate) or a sick or deceased person who has been infected with the Ebola virus can cause EVD in humans.

Vesicular stomatitis virus, which is present in Ervebo, has been attenuated and altered to incorporate a protein from the Zaire Ebola virus. The vesicular stomatitis virus itself doesn't have much of an impact on people. Only one protein from the Zaire Ebola virus is included in the vaccine, which cannot spread the illness.

As Beta cells have a massive production and secretion of insulin, the endoplasmic reticulum and ribosomes have a greater concentration so as to satisfy the demand of the hormone in the body.

What are beta cells?

Beta cells are found in a cluster of cells in the pancreas called pancreatic islets. These cells synthesize, produce and secrete insulin. Glucose levels in blood are regulated by the hormone Insulin.

Beta cells secret the stored insulin and increases production of the hormone when the glucose levels rise in the blood(during digestion).

The response to spike in glucose levels in blood takes like 10 minutes.

These beta cells are either attacked or destroyed by the immune system in people with diabetes or they cannot produce an enough amount of insulin that is required for control of blood sugar levels.

Therefore, as Beta cells have a massive production and secretion of insulin, the endoplasmic reticulum and ribosomes have a greater concentration so as to satisfy the demand of the hormone in the body

Answer:

A concentration gradient must exist.

Explanation:

For diffusion to occur, a concentration gradient must exist. Therefore, the correct option is A.

The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.

Without the use of energy, molecules can be transported from an area of high concentration to an area of low concentration through the process of diffusion. Simple diffusion and Complex diffusion are the two types of diffusion. Diffusion was made easier.

Students may investigate the features Mendel tested and then cross two pea plants to observe what offspring they create in this area of the online lab.

Mendel's experiment:

"Plant five pea plants and see what they look like," Mendel advises pupils. The animated Mendel plants and waters five pea plants when students click the "Plant" button. Each pea plant shoots quite fast. The learner may view the pea pod's color, shape, and form, as well as the color and form of the mature seed, by moving the pointer over the plants.

Although the plants are selected at random each time the application is run, all of the numerous varieties of pea plants may be observed in these growing peas. Mendel quizzes the pupils on how many distinctive characteristics they notice in the plants after they have grown five plants

He shows there are seven distinct qualities :

They can cross any plant with itself or with another plant using the five plants they raised. The way that qualities are passed down to future generations may start to show certain patterns to students. They might know, for instance, that a plant with white flowers crossed with itself or another plant with white flowers will only produce plants with white flowers, whereas a plant with purple flowers crossed with itself or another plant with purple flowers will occasionally produce plants with white flowers. You could discover that by encouraging students to focus on specific characteristics during their experiments, they start to see these patterns on their own.

The accurate descriptions are as follows: For question 44, none of the options accurately describe the likely finding when a failure to record an accrual occurs. For question 45, the accurate description is option (d): all of the above. For question 46, the correct first step to find errors in an unbalanced trial balance is to work from the ledger to the trial balance and verify the correct transfer of ledger account balances, which corresponds to option (c).

It appears that the text provided contains several errors and inconsistencies. However, I will attempt to address the questions based on the context and assumptions made.

44. The inaccurate description of the failure to record an accrual that is likely to be found is option (c): A review of the trial balance reveals that an asset or liability account that is normally present after several are recorded is not present. In reality, if an accrual is not recorded, it would lead to an understatement or omission of expenses or revenues, not the absence of assets or liabilities in the trial balance.

45. A comparison of this year's trial balance with last year's may be a good way to discover whether normal accruals or deferrals were made this year and whether errors in the accurate or deferred recognition of revenues or expenses have resulted in over- or understatement. Therefore, the correct option is (d): all of the above.

46. When trying to find errors in a trial balance that does not balance, the first step should be to work from the ledger to the trial balance to verify that ledger account balances were transferred to the correct debit or credit columns. This option corresponds to option (c).

The statement suggests that less than one-third of the citizens' favorite positions are equal to the median favorite position.

Hotelling's model is a spatial model of political competition where candidates position themselves along a one-dimensional policy space to maximize their vote share. In this variant, with the inclusion of the option to stay out of the race, candidates have the opportunity to avoid losing by not participating. However, staying out of the race is still considered less favorable than tying for first place.

The statement indicates that less than one-third of the citizens' favorite positions are equal to the median favorite position (m). This suggests that there is a concentration of citizen preferences on positions other than the median. The specific distribution of citizen preferences and its implications would depend on the exact positioning of the candidates and the nature of voter behavior.

Overall, this variant of Hotelling's model introduces an additional option for candidates to stay out of the race, which affects the dynamics of competition and the distribution of citizen preferences. The statement about the concentration of citizen preferences highlights a departure from a symmetric distribution and adds complexity to the strategic choices and outcomes in the model.

I) 200 per mm^2

ii) there will be more water loss via transpiration

Explanation:

I) as you can see there are 2 stomata

calculate the area of the surface:

0.1 × 0.1 = 0.01mm^2

2 ÷ 0.01 = 200

Part 1: The number of stomata per mm^2 is 200 mm^2

Part 2: The disadvantage of this seemingly large surface area is that the leaf tends to loss more water by transpiration

Part 1:

First, find the area

Area = length * width

Area = 0. 1* 0. 1 = 0.01 mm^2

Stomatal number of a leaf is the average number of stomata per square millimeters of epidermis of the leaf.

Number of stomata per mm^2 = number of stomata / area in mm^2

Note that the number of stomata from the diagram is 2

Number of stomata per mm^2 = 2/0. 01 = 200 mm^2

Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms.

Answer:

V₂ = 1.32  L

Explanation:

Given data:

Initial volume = 1.25 L

Initial pressure = 0.865 atm

Final volume = ?

Final pressure = 0.820 atm

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

0.865 atm × 1.25 L = 0.820 atm × V₂

V₂ = 1.08 atm. L/ 0.820 atm
