Answer:

when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.

Explanation:

If there was no water available for photosynthesis, the cellular level of the

plant will be affected negatively in areas such as shrinking of cells and

decrease in photosynthetic activities.

Plants require water to produce food in the process known as

photosynthesis. When there is no water the photosynthesis is slowed down

and the cells begin to shrink.

The shrinking of cells then results to the wilting and yellowing of leaves of the plant.

Answer:

DNA is the genetic information used to make proteins, and it contains the hereditary traits of organisms. There are two types of DNA: mitochondrial DNA, which you can only get from your mother, and nuclear DNA, which is a combination of both your ancestors' DNA.

Answer:

If the solute carries a net charge, however, both its concentration gradient and the electrical potential difference across the membrane, the membrane potential,influence its transport. ... Thus, transport by carriers can be either active or passive, whereas transport by channel proteins is always passive.

Explanation of previously stated factors resulting in a declining bee population.

Explanation:

The user should submit further information on why the bee population is declining. My personal recommendation would be to introduce a reason and then explain it.

In response to your stated reasoning(s), assuming they are correct, this would be giving information such as:  What can pesticides do to bees? What are some statistics showing habitat destruction. What do bees need to be nourished?

I would not recommend ending your answer with "and more".

Answer:

Habitat isolation occurs when habitat preferences lower the probability of mating between individuals associated with differing habitats. While a potential barrier to gene flow during ecological speciation, the effect of habitat isolation on reproductive isolation has rarely been directly tested.

Answer:

A. To gather and respond to information

Explanation:

Answer:

The similarities and differences between DNA and RNA are given as follows:

Explanation:

Similarities:

Both are made up of nucleotides

Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.

Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines

Purine binds with pyrimidines

Differences

DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring

RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.

DNA is double-stranded while RNA is a single-stranded

Under alkaline conditions, DNA is stable while RNA is not stable.

Answer:

25%

Explanation:

If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:

DD, Dd, Dd, dd

In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)

The chance that the puppy will be deaf is 25%. The correct option is B.

The term "allele" refers to the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to categorize the alleles.

We usually refer to them as normal or wild-type alleles, or abnormal or mutant alleles.

If they are both heterozygous, they have the Dd genotype. As per the Punnett square Dd x Dd, one can see the the following genotypes for the puppy:

DD, Dd, dD, dd

Because deafness is recessive, the puppy must be dd, which is 1/4 of the population.

Thus, the correct option is B.

Answer: Kathrin Plath and William Lowry

Explanation:

Kathrin Plath and William Lowry and researchers at the University of California in Los Angeles(UCLA) were able to reprogram adult cells to become develop properties of embryonic stem cells which are very important as they can become any type of cell in the body which can have very important implications in medicine.

They did this by genetically altering the cells to enable them age backwards to a point where they were like the aforementioned stem cells.

Explanation:

Answer:

Yes.

Explanation:

Yes, measurements should be more accurate if these scientific error are removed. Yes, we must perform more trials in order to verify the experiment. Environmental factors, such as the laboratory's lighting or temperature, has a great effect on the experiment and can cause error. In this experiment the errors occur such as instrumental, environmental, procedural, and human. All these error causes inaccurate readings of experiment so greatly affect the experiment.
