Explanation:
The enormous genetic diversity of HIV is largely the result of its______, and it has made it especially difficult to create a(n) ________ against the virus.
A. high mutation rate; antibiotic
B. high mutation rate; vaccine
C. low mutation rate; antibiotic
D. low mutation rate; vaccine
Answer:
B. high mutation rate; vaccine
Explanation:
The enormous genetic diversity of HIV is largely the result of its high mutation rate, and it has made it especially difficult to create a vaccine against the virus.
This ultimately implies that, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
Hence, the human immunodeficiency virus (HIV) possesses a high error rate

Erythrocytic schizogony refers to asexual reproduction of a parasite in erythrocytes (red blood cells).
A new pest is found that only feeds on corn plant leaves. Livestock eat corn cobs. Which promoter would you choose if the modified gene produces toxins that are not safe for livestock to ingest?
Answer:
Promoter 2
Explanation:
Promoter 2 is the best choice because the resistance gene will only be expressed in the leaves of the corn plant. Promoter 3 only expresses genes in the corn roots, so the toxin would not be available in the leaves for the pest to eat. Promoters 1 and 4 would express the resistance gene in the leaves of the corn plant, but the toxins would be expressed in the corn cobs as well, which may then be fed to livestock.

Write a grammatically correct sentence that compares the reactants and products of photosynthesis with the reactants and products of respiration.
Answer:
The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis
"The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis" is a grammatically correct sentence that compares the reactants and products of photosynthesis and respiration.
Photosynthesis and respiration depend on one another as products of photosynthesis act as reactants in cellular respiration, whereas products of cellular respiration react as reactants of photosynthesis.
Photosynthesis:
Photosynthesis is the process takes place in green plants that produce sugar molecule and oxygen by reacting carbon dioxide and water in presence of the light. Energy (sunlight), H₂O, and CO₂ are reactants of this process that come from respiration. Sugar and O₂ are released as products that use in cellular respiration as reactants.Cellular respiration:
Process of cellular respiration use sugar molecule and oxygen to react together to form energy in the form of ATP by releasing carbon dioxide and a water molecule. Sugar and O₂ are reactants of this process that come from the photosynthesis process. Energy (ATP), H₂O, and CO₂ are released as products that use in photosynthesis as reactants.Thus, the grammatically correct sentence "The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis"

Two models of molecules are shown. Two models of molecules. One on left is made of one carbon and one oxygen atom. One on right is made of one carbon and two oxygen atoms. What is true about the molecules shown in the models? A. They are molecules of the same substance. B. They are molecules of two substances with the same properties. C. They are molecules that join together. D. They are molecules containing the same kind of atoms.
Answer/Explanation:
CO and CO2 are both carbon poisoning. They both are odorless, colorless, and potentially deadly. But the chemical difference(extra oxygen molecule) causes it to be a different substance. CO is carbon monoxide while CO2 is carbon dioxide. CO2 is common because it is what we exhale after a breath, it is used to keep plants alive. On the other hand CO is caused by gas emissions and lack of oxygen. They may sound the same but they are just two different molecules containing the same types of atoms.

Which color on the image of the periodic table
corresponds with the transition metals.
Blue
Red
Black
Orange
So yellow is mostly the classification of Metal, But I don't see that option here. Answer-Blue
Blue color of the periodic table image represent transition metal. Thus, option A is correct.
What are transition metal ?The metal which have valence electrons that can participate in the formation of chemical bonds called as transition metal.
In a periodic table the position of transition metal is the long middle portions of the periodic table and form Groups 3 elements through 12.
These are paramagnetic metals, a good conductors of heat and electricity, in a solution their compounds are brightly colored when hydrated.
Every transition metal has multiple positive oxidation states, hard solid with high melting points and boiling points.
The elements are dense, less reactive but are good catalysts which form complexes with molecules called ligands.
Transition metal ions have incomplete filled d-orbitals, except for scandium
Some of the transition metals are iron, chromium, vanadium, titanium, cobalt, nickel, tungsten, gold, and platinum.
Thus option A is correct.

Why are there two copies of each chromosome? Question 5 options: One copy comes from each parent Chromosomes were duplicated in mitosis The chromosomes copied themselves through DNA replication
Answer:
One copy comes from each parent
Explanation:
The correct answer would be that one copy comes from each parent.
During gamete formation, the chromosome number in the sex cells is usually halved to produce haploid gametes. Haploid gametes fuse together and donate their chromosomes to form a diploid zygote during the fertilization process. Hence, one copy of the two chromosomes in diploid organisms comes from each parent.

The process whereby plants capture energy and make complex carbon based molecules is known as
a. photosynthesis.
b. development.
c.evolution.
d. homeostasis.
Answer:
I'm not exactly sure cause I learned this along time ago, but I think its D.
Explanation:
Evolution is not accurate, and development has nothing to do with creating energy or making complex carbon. Photosynthesis seems like the right answer but that's when a plant absorbs sunlight and water to make glucose and oxygen.

Explain the different motions of Earth and how they cause days, years and seasons.
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun).
hope it helps
Answer:
The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial precession).
Explanation:
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun). Seasons are largely due to factors surrounding the Earth's tilted axis as it revolves around the sun. A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly.
