B.
Chromosomes are threadlike structures that carry genetic information.
C.
Humans receive the majority of their chromosomes from their mother.
D.
Chromosomes are arranged in 20 distinct pairs in the human body.
Please select the best answer from the choices provided
A
B

D
Answers
Answer:
B. Chromosomes are threadlike structures that carry genetic information
Explanation:
Normally developed humans carry about 46 chromosomes in each cell, so A is false.
The numver of chromosomes is equal from the mother and the father, so C is false.
Chromosomes are arranged in 23 distinct pairs, so D is false.
The statement that best describes chromosomes is: Chromosomes are the threadlike structures that carry the genetic information.
What is a chromosome?It is a structure that is present in both prokaryotes and eukaryotes and is composed of nucleic acid (DNA) and proteins. It is responsible for genetic information.
Facts about chromosomes:Humans have 46 chromosomes in all somatic cells, and the reproductive cells except in the sperm and ova, which are haploid with 23 chromosomes only. Humans receive one set of 23 chromosomes from their mother and the other set from their father.Chromosomes are arranged in 23 distinct pairs in the human body.Hence, option b) is the correct option.

A cart accelerates at 2 m/s2 when a force of 60 N is applied. What is the mass of the cart? (Formula: F=ma)
0.03 kg
30 kg
62 kg
120 kg
Answers
Answer:
30 kg
Explanation:
Since a force of 60 N is applied, the mass of this cart is equal to 30 kg.
Given the following data:
Acceleration = 2 [tex]m/s^2[/tex]
Force = 60 Newton.
How to calculate the mass of this cart.From Newton's Second Law of Motion, the force exerted on the cart is given by this formula:
[tex]F=ma[/tex]
Where:
F is the force.m is the mass.a is the acceleration.Making mass the subject of formula, we have:
[tex]m=\frac{F}{a}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m=\frac{60}{2}[/tex]
m = 30 kg.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answers
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?
A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.
Answers
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
D Nothing has to happen to the glucose. Plant cells can use it as is.
What happens to the glucose produced by plants?Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.
In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.

7. A solvent is a substance that dissolves a solute, resulting in a solution (able to dissolve other substances). A solute is the dissolved matter in a solution. The key difference between solvent and solute is that the solute is the one to be dissolved while, the solvent is responsible for dissolving it.
