If a plant undergoes mutation and cannot produce Casparian strips, what process won't it be able to do?

QUESTION POSTED AT 18/01/2020 - 06:17 AM

Answered by admin AT 18/01/2020 - 06:17 AM

One of the possible things that would happen in a plant mutation, is it stops the formation of the Casparian Strips is the lack of water and food in plants. The Casparian Strips is the impermeable layer that helps absorb water in plants and dissolves some of the minerals needed for plants to survive.

What process is similar in both fermentation and cellular respiration?

Answer:

Similarity in fermentation and cellular respiration:

Both the fermentation and cellular respiration process includes the same enzyme and the break down of glucose till the pyruvate molecule is same in these process. ATP is produced at the end of the process but the number of ATP varies in both the process.

The fermentation and cellular respiration takes place in the living organisms. Both the process includes the cytoplasm as their site of respiration. The oxidation of NADH to NAD+ occur in both the cellular respiration and fermentation process. The glucose is broken down in both the process.

Earth receives thermal energy from the sun via radiation. Which of the following is a result of this energy transfer?A. There is matter to produce carbon compounds on Earth.B. Earth is a closed system in terms of energy.C. There is energy to support life on earth.D. Energy is created but not destroyed in the earth system

Answer: C. There is energy to support life on earth.

The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.

What would happen if solid water were denser than liquid water? A. Plants would wilt. B. Solid water would float on the surface of bodies of water. C. Bodies of water would freeze from the bottom up. D. Water would escape from the atmosphere.

Answer: C. Bodies of water would freeze from the bottom up.

Explanation:

The water in the form of ice exhibit low density as compared to the water in the liquid form. Hence, the ice will float over the surface of water if ice is kept in water.

But according to the given condition, the solid water that is actually the ice will be denser than the liquid water. Thus the solid water will sink at the bottom of the liquid water. As a consequence the bodies of water would freeze from the bottom.

A green plant absorbs a toxic substance that completely blocks the production of ATP. How would this most likely affect the dark reactions? A - The dark reactions would stop happening. B - The dark reactions would produce more NADPH C - The dark reactions would continue to produce oxygen D - The dark reactions would produce more carbon dioxide

Answer:

The most appropriate answer would be  A - The dark reactions would stop happening.

Light-independent or dark reaction or Calvin cycle is a part of photosynthesis in which products of light-dependent reaction (ATP and NADPH) are used to fix carbon from carbon dioxide into glucose.

It takes around 9 molecules of ATP and 6 molecules of NADPH in order to produce 1 molecule of glucose.

So, if ATP production would be stopped in a plant then dark reaction would also stop happening.

Black and white coloration in cows is dominant to brown and white. Black and white cows were crossed over several years and the following offspring were produced: 8 black and white and 3 brown and white. What is the MOST probable genotype of each parent? A) BB X BB B) BB x bb C) Bb x Bb D) Bb x bb

The answer is C) Bb x Bb

B - the allele for black and white coloration
b - the allele for brown and white coloration

There are in total 11 offspring (8 black and white and 3 brown and white),
In a monohybrid cross when both parents are heterozygous (Bb), the phenotype ratio is 3:1. We have ratio 8:3.

The ideal ratio would be 9:3 because it is the same as 3:1.
Therefore, the parents Bb and Bb will have 
8 black and white and 3 brown and white with the ration 8:3 ≈ 9:3 = 3:1

Succession is a process that allows communities to recover from disruptive events. c. The process of succession is necessary to maintain and establish stable communities. d. Succession can follow both human and natural events.

Answer: a.  Succession is the cause of ecosystem destruction.

Explanation:

An ecological succession can be define as a change that occur in the biotic community of the ecosystem with respect to the changes that occur in the surrounding environmental factors with respect to time until the ecosystem attains stability.

Succession is the cause of the ecosystem destruction is not true about the succession this is because of the fact that an ecological succession is a natural process that aids in the development of the ecosystem instead of it's destroying it. It initiate to provide the stability to the living species and their surrounding environment.

Which process MUST occur before mitosis and meiosis can occur

Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups is a process that can be observed in virtually all eukaryotic cells. Interfase must happen before mitosis can begin. Interfase is when the parent cell stores energy and becomes bigger so it can make the two daughter cells.

Which ocean process exposes the coastal aquatic organisms to land-based predators?

The correct answer is - Tidal patterns.

The aquatic organisms that live very near the coast are becoming exposed to land and air predators in certain parts of the day, and the reason for that are the tidal patterns. The tidal patterns are simple, in certain part of the day the water comes more towards the land, while in other parts of the day it retreats back towards the sea/ocean. The problem for the aquatic organisms comes when the water is retreating, as they have brought more inland previously, and than they end up trapped on the land or in small pools of water. That situation makes them a very easy pray for the land and air animals, which over time had learned the tidal patterns and patiently wait for the retreat of the water and have a nice aquatic meal.

Answer;

-Extrusive igneous rock

When molten rock undergoes crystallization above ground, it results to an extrusive rock.

Explanation;

-Crystallization is one of the three processes that change one rock to another in the rock cycle, other are; metamorphism, and erosion and sedimentation.

-Igneous rocks are rocks formed from the crystallization of a liquid (molten rock). Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth's surface.
