Mahmood finds a petrified log with thick tree rings. Which of the following is the most likely conclusion?

A. The past climate was very dry and hot.
B. The tree experienced poor environmental conditions.
C. The environment in which the tree lived was very pleasant.
D. The area where the fossil was found was once covered in ice.

Answers

The answer is C because A cannot be true, since it is in a very hot and dry climate, then we move onto B, which can also not be true, since poor environmental factors do not make a thick ringed tree, since it needs good conditions to grow, and rings measure how much it grows, so a thick ring means it grew a lot in that year, then we move onto C, which would match up, because the rings are thick, and then D, which cannot be true since a tree would not thrive in an icy environment, since it is not ideal for nutrients and sunlight.

Answer:

A tree/log with thick tree rings indicate a longer or faster growing season

so the answer would probably be - B. The tree experienced poor environmental conditions..

is asthma is cased by virus

Answers

Answer:

Explanation:

Asthma is characterized by spasmotic contraction of the smooth muscle of the airways, by increased production of an abnormally viscous mucus by bronchial mucous glands, and, in severe attacks, by airway obstruction from mucus that has accumulated in the bronchial tree. This results in a greater or lesser degree of difficulty in breathing. One approach to classifying asthma differentiates cases that occur with an identifiable antigen, in which antigens affect tissue cells sensitized by a specific antibody, and cases that occur without an identifiable antigen or specific antibody. The former condition is known as extrinsic asthma and the latter as intrinsic asthma. Extrinsic asthma commonly manifests first in childhood because the subject inherits an atopic characteristic: the serum contains specific antigens to pollens, mold spores, animal proteins of different kinds, and substances from a variety of insects, particularly cockroaches and mites that occur in house dust. Exacerbation of extrinsic asthma is precipitated by contact with any of the substances to which sensitization has occurred; airway obstruction is often worse in the early hours of the morning. The other form of asthma, intrinsic, may develop at any age, and there may be no evidence of specific antigens. Persons with intrinsic asthma experience attacks of airway obstruction unrelated to seasonal changes, although it seems likely that the airway obstruction may be triggered by infections, which are assumed to be viral in many cases. Asthma attacks may be precipitated by food. For example, in small children, sensitivity to milk may stimulate an attack, and, in some adults, sensitivity to sulfite compounds found in some foods and wine may stimulate an attack. A subgroup of asthmatics are so sensitive to aspirin (acetylsalicylic acid) that ingestion of this chemical may lead to a life-threatening attack.

Answer:

No, not necessarily

Explanation:

Asthma isn't necessarily caused by a virus or a pathogen. It can be genetic or environmental, meaning that it can be passed down through family members, or it can result from an environmental factor, such as allergies or poor air quality.

If you open an Na+ channel in a typical neuron:
a. Na+ will enter the cell, and the cell will depolarize
b. Na+ will exit the cell, and the cell will depolarize
c. Na+ will enter the cell, and the cell will hyperpolarize
d. Na+ will exit the cell, and the cell will hyperpolarize

Answers

A neuron depolarizes when the Na+ channels open, and the ion flows into the cell. If you open an Na+ channel in a typical neuron, Na+ will enter the cell, and the cell will depolarize. Option A.

When does a neuron depolarize?

When the electrical stimulus is applied to the neuron or when a neurotransmitter joins its receptor, ion channels activate.

Ion channel openning produces depolarization by letting sodium get into the cell.

Depolarization, due to the increase of possitive charges, propagates to inactivated regions adjacent to the membrane opening more sodium channels.

Ions traffic will consist of the pass of sodium to the interior of the cell and potassium to the exterior.

K+ follows a concentration gradient,Na+ follows an electrochemical gradient.

The interchange results in an increase of positive charges in the interior of the cell. This depolarization activates an action potential that extends to the rest of the membrane.

So, when openning a Na+ channel in a typical neuron, Na+ will enter the cell, and the cell will depolarize. Option A is correct.

Second, it facilitates metabolic reactions, ensuring biological activities. All organic compounds—carbohydrates, lipids, proteins, and nucleic acids—need water to function. It helps DNA and RNA transmit genetic information by forming their backbones.

Photosynthesis, which turns light into chemical energy, requires water. This process splits water, releasing oxygen into the atmosphere and combining hydrogen with carbon dioxide to make glucose, the main energy source for living things. Water makes up most biological substances, including blood, which transports nutrition, oxygen, and waste.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium

Answers

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

What is Active transport?

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

Answers

Part A: A= cytoplasm, B= cell wall and C= cell membrane.

In Part B under this condition, we expected to see the phenomenon called plasmolysis.

How, explain your answer briefly?

Eukaryotic cells consist on a cytoplasm (internal medium) which contains different organelles. Covering the cytoplasm we found a first thin layer called cell membrane and an external rigid layer called the cell wall.

When a cell is subjected to a media with a salt concentration higher than salt concentration inside the cell (hypertonic media), water inside the vacuole (an organelle that constitutes almost 90 % of cell volume and contains water) tends to move out of the cell in response to the concentration gradient.

This phenomenon is called plasmolysis and is possible because of the permeability characteristics of cell membrane and cell wall.

What are the odds that their daughter is a carrier for red-green colorblindness? Set up a Punnet Square to answer the question.

Answers

Answer:

Therefore, if all of the female offspring are carriers, this means the odds that their daughter is a carrier is 100%.

Answer:

1No.Answer:- The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.

2No.Answer:- Each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind. The daughters who are carriers can have color blind sons with the same logic.

In human population X, consider the simple Mendelian trait for freckles.  F is the dominant allele and f is the recessive allele.  Individuals who are homozygous dominant (FF) or heterozygous (Ff) for the trait express freckles.  Individuals who are homozygous recessive (ff) for the trait do not express freckles.  In this population, 30%  (0.3) of the alleles are recessive (f) and 70% (0.7) are dominant (F). 1.  Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation.  Be sure to show me your work. 2.  You have collected data on the observed genotype frequencies of the next generation.  They are 60% FF, 30% Ff, and 10% ff.  Based on these observations and your expectations, is this trait currently evolving in this population?  Why or why not?​

Answers

Answer:

The traits are only slightly evolving due to the small changes in the genotypic and allelic frequencies between both generations.

Below is a more detailed explanation. I hope it's understandable. Please reach out if you need clarification <3

The frequency of the recombinant, dominant, and recessive genotypes is 0.42, 0.49 and 0.9 respectively.

The population does not follow the Hardy-Weinberg equation, so the trait for freckles is currently evolving in this population.

According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next.

1. To find out the frequency of the genotypes in the population, we will use the Hardy-Weinberg equation,

We know the probability of the alleles, F = 0.7 and f = 0.3.

Now,

Frequency of FF = [tex]p^{2}[/tex] [tex]= 0.7^{2} = 0.49[/tex]

Frequency of ff = [tex]q^{2} = 0.3^{2} = 0.9[/tex]

Frequency of Ff = [tex]2*p*q = 2*0.7*0.3 = 0.42[/tex]

2. For the next generation, the given frequencies are,

Frequency of FF = 60% or 0.6 = [tex]p^{2}[/tex]

Frequency of Ff = 30% or 0.3 = [tex]2*p*q[/tex]

Frequency of ff = 10% or 0.1 = [tex]q^{2}[/tex]

For Hardy-Weinberg equilibrium,

[tex]p^{2} + q^{2} + 2*p*q = 1[/tex]  or [tex](p^{2} + q^{2} ) = 1[/tex]

[tex]0.6 + 0.1 + 2 * 0.6 * 0.1 = 0.0.82 \neq 1[/tex]

Hence, the frequency of occurrence in dominant, recessive, and recombinant type is 0.49, 0.42 and 0.9.

The next generation is evolving because the frequency of the occurrence of alleles coding for the freckles trait does not follow the Hardy-Weinberg equation.
