Answer: We know that genes play an important role in shaping how we look and act and even whether we get sick. Some traits are controlled by genes passed from parent to child, others are acquired through learning but most are influenced by a combination of genes and environmental factors.

Explanation:

Genetics helps to explain: What makes you unique, or one of a kind. Why family members look alike. Why some diseases like diabetes or cancer run in families.

High-latitude ocean water tends to support large planktonic communities because ________. of higher dissolved carbon dioxide the
aleksklad [387]

Answer: They tend to support large planktonic

communities because (of higher dissolved oxygen and nutrient concentrations).

Explanation:

Planktonic communities are made up of basic organisms that forms the oceanic food web. They are broadly divided into Phytoplankton (these are the producers), Zooplankton (these are the consumers) and Bacterioplankton (these are the recyclers).

High-latitude ocean water is mostly affected by the quantity of oxygen and nutrients it contains. Large planktonic communities thrives in these aquatic environment because is contains higher amount of dissolved oxygen and nutrient concentrations which forms part of their basic needs for survival. This is so because changes in ocean water can impact all levels of the food web. Increase or decrease in ocean temperature can modify the plankton diversity and distribution directly by altering it's metabolic rates and growth.

Therefore due to the geographic location of high latitude ocean, higher dissolved oxygen and nutrient concentrations favour the survival of a larger planktonic communities than other ocean parts.

Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply. View Available Hin
nataly862011 [7]

Answer:

Acetylation of histone tails is a reversible process.

DNA is not transcribed when chromatin is packaged tightly in a condensed form.

Methylation of histone tails in chromatin can promote condensation of chromatin.

Acetylation of histone tails in chromatin allows access to DNA for transcription.

Eukaryotic chromatin structure is a highly complex assembly which needs to be simplified in order to undergo process of transcription. Eukaryotic chromatin structure is highly condensed in nature and DNA cannot be access for transcription. Actylation of histone tails is a process in which breaks the bond of attraction between adjacent nucleosomes. It results in chromatin being condensed attains a loose form. Transcription of DNA can occur in a loose chromatin. Methylation can promote condensation or decondensation of chromatin structure depending upon the methyl group present in the histone.

This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.
faltersainse [42]

Answer:

Primary active transport

Explanation:

Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump  is an example  of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).

BRAINLIEST 20 POINTS ANSWER THESE QUESTIONS
yarga [219]
1. An underdeveloped DNA molecule would result in mutations. On the genetic level, this could mean entire traits are deleted or that an early stop occurs in transcription, which could cut off parts of instructions.

2. Genetic code is the nucleotide sequence of a gene while the gene expression is how these sequences are used to make functioning amino acids and proteins to create DNA.

3. In each cell itself there are roughly 42 million proteins.
