Answer:

A. Small size.

B. A single cell or unicellular.

C.it has one chromosome which is not true and it is called plastid.

Explanation:

This is because prokaryote are unicellular organisms that lack nucleus and membrane bound organelles. The are smaller in size compare to eukaryotic, which have large surface to volume ratio. They lack mitochondria, Golgi apparatus, endoplasmic recticulum, e t.c. They have only one chromosomes which is not even a true one and it is called plastid. Examples of prokaryote include bacteria.

Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Explanation:

In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.

Answer:

b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.

Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.

The male is XY and colour blind, so genotype cY

Male offspring can be cY or CY so p|colourblind = 50%

Female offspring can be Cc or cc so, again p= 50%

If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

Fungi

Explanation:

Answer:

40kg

Explanation:

F=M*A

M=F\A

M=400\10

M=40kg

The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2​ is 40 kg.

The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.

It is a vector quantity whose direction, strength, or magnitude match a plumb bob.

According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.

We know that,

F = m x g

m = f/g

Where,

F = force

m = mass

g = acceleration due to gravity

Given that,

F = 400N.

g = [tex]10m/s^2[/tex]

So,

m = 400/10

m = 40 kg.

Thus, the mass is 40 kg.

The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.

Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.

An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.

Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Answer:

Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine

Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.

Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.

Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

Salmonella infection and campylobacteriosis cause diarrhea after eating partially cooked chicken. This causes food poisoning.

An illness called food poisoning is brought on by consuming tainted food. Most people recover without treatment in a few days and it's typically not dangerous. The food is typically contaminated with bacteria, such as salmonella or Escherichia coli (E. coli), or a virus, like a norovirus, in cases of food poisoning.
