Answer:

Congestive Heart Failure.

Explanation:

Congestive heart failure may be defined as a type of the chronic condition that might affect the pumping of the heart muscles. The fluid gets accumulated in the heart.

The congestive heart failure cannot be easily marked in youngsters but can be marked easily in the old persons. The individual feels difficulty in breathing and may also suffer from the tachycardia. Excessive sweating and change in the nail color is common in severe heart failure.

Thus, the correct answer is option (D).

amm1812

Answer:

<u>Summarized data</u>

Explanation:

A data summary provides a comprehensive report of experimental findings. This makes the analysis of data easier by answering key research objectives outlined in the experimental procedure.

Also, summaries allow for tracking trends and procedural changes, observations and potential limitations; this makes arriving conclusions much easier.

In an aquatic ecosystem, the aquatic plants are eaten by small invertebrates that in turn are eaten by crayfish, which are eaten
makvit [3.9K]

Answer:

Aquatic plants

Explanation:

Aquatic biomass is energy crops which do not remain competitive for territory or any other energy with food plants. Aquatic biomass consists of various micro, macro- and aquatic plant species. The highest priority has been given to HTL treating aquatic biomass because microalgae are suitable for use and can potentially deliver the highest levels of biomass per area. Aquatic biomass, such as seaweed, algae and aquatic plants, is likely to achieve part of the growing biomass want.

LiRa [457]

<u>Full question:</u>

Thousands of years ago, giraffes with short necks were common within giraffe populations. Nearly all giraffe populations today have long necks. This difference could be due to

giraffes stretching their necks to keep their heads out of reach of predators

giraffes stretching their necks so they could reach food higher in the trees

a mutation in genetic material controlling neck size occurring in some skin cells of a giraffe

a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe

<u>Answer:</u>

This difference could be due to:a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe

<u>Explanation:</u>

The primary short-necked forms contained large, mutable populations. Following the selection pressure of desiccations and leaf deficiencies, those changes with longer necks and forelegs sustained and repeated preferentially. In this procedure, throughout generations, these large mammals have occurred, being acclimated to their unique environment .

Lamarckian theory illustrated giraffe neck metamorphosis by showing that consistent stretching gradually extended their necks, and that they then moved on these propitious longer necks to their offspring. Environment and other variations created the extirpation of the eurasian giraffids, but various African species endured.

A cross between two plants that both have yellow flowers produces 80 offspring plants, of which 38 have yellow flowers, 22 have
zvonat [6]

Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.

1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.

1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.

3:1 is the phenotypic ratio for complete dominance.

2:1 is the phenotypic ratio for lethal recessive.
