Answer:

The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.

Explanation:

According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
So, by performing the calculation, $\bold{\mathrm{F}=30 \times 0.4 \mathrm{N}=12 \mathrm{N}}$
12N force will move the boy along with the wheel chair.

The answer is B.

These elements are among the most important elements in life. Most of these elements are also non-metals. Elements life sulfur and nitrogen combine with carbohydrates to form among acids rings like cysteine. Carbohydrates combine with phosphorus to form molecules such as the DNA backbone chain.

lesantik [10]

Answer:

The correct answer is A) Histone deacetylation generally decreases gene expression.

Explanation:

Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.

In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.

<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>
