All of these can contribute to sediment accumilation in bodies of water.

Sedimentation accumulation found in water bodies can be the result of fertilizer runoff, pesticides, pesticides, and erosion from agricultural practices. So, the correct option is D.

The sedimentation accumulation may be defined as a process of gathering sediments into the rocks, and water bodies, and increasing their actual mass.

Sedimentation accumulation may be carried by the runoff of fertilizers, pesticides, and insecticides. It also occurred due to the process of soil erosion that takes place during agricultural practices.

Therefore, the correct option for this question is D.

The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.

A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.

Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).

So, the correct answer is 'Monosomy'.

Answer:

When Frederick Griffith discovered two strains of Streptococci in 1923, the bacteriologists were intrigued by the differences between them: the S (smooth) strain, which produces colonies that are smooth and shiny on a lab plate; the R (rough) strain, which lacks a polysaccharide coat and produces colonies that are rough and irregular on a lab plate.

Answer:

Exons.

Explanation:

In mRNA maturation and processing, a complex called a splicesome essentially "cuts out", if you will, non-coding parts of the DNA sequence to be translated. The parts that are cut out are called "introns", and the parts that are left over that code for a protein sequence, are called "exons". Careful with the terminology. It seems counterintuitive that exons are the ones that stay (exon = exit? NO.) and introns (in, as in, stays in? NO.) are the ones that are cut out of the mature mRNA. Perhaps you can remember that the terms seem to be the opposite, that's how I remember it. Alright, good luck with all of this.

Metastases most commonly develop when cancer cells break away from the main tumor and enter the bloodstream or lymphatic system. These systems carry fluids around the body.

Explanation:

In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body.

Answer:

negative, salt

Explanation:

ADH functions via a negative feedback mechanism that responds to blood salt concentration to maintain homeostasis.

In order to maintain a constant state between internal conditions and the external environment, a cell's response to its environment is known as homeostasis.

Because of their complexity and uniqueness to living things, the coordinated physiological responses that keep the majority of the body's dynamic equilibrium in place have been given the name "homeostasis."

Ex: When it's cold outside, we start to shiver and use energy to stabilize our body temperature. This is where the cell regulates cell temperature, fluid balance, sugar balance, etc. through it.

Therefore, there is negative feedback that responds to blood salt concentration.
