How can the type of bedrock under soil affect the characteristics of the soil? *
by absorbing water
by making the soil more fertile
by weathering and becoming new parent material
by providing surface area for nutrient accumulation
Answer:
by weathering and becoming new parent material
Explanation:
Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.

What is the relationship between the levels of CO2 in the atmosphere and the levels of CO2 in the ocean?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1
What is pollinization?
Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.
What are the Feminine reproductive structures?The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.What are the Masculine reproductive structures?The pollen grains, or male séx cells, are produced in the stamens.The stamen has an anther where the pollen is produced, and a filament that provides support.What is fertilization?Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.
During fertilization
1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.
2) Once in the stigma, the pollen grain germinates.
3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.
4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.
5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.
6) The zygote develops in the ovary.

A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.
What is antagonist muscle?muscles can only pull. They typically work a joint in pairs because of this. When a body part is moved, one of the pair's muscles contracts; when the body part is brought back to its starting position, the other muscle in the pair contracts.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.
Therefore, A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.

Two genes control color in corn snakes as follows: O- B- snakes are brown, O- bb are orange, oo B- are black, and oo bb are albino. An orange snake was mated to a black snake, and a large number of F1progeny were obtained, all of which were brown. When the F1 snakes were mated to one another, they produced 100 brown offspring, 25 orange, 22 black, and 13 albino.a. What are the genotypes of the F1 snakes
Answer:
The correct answer is - OoBb
Explanation:
As it is given that:
O- B- snakes = brown
O- bb = orange
oo B = black
oo bb = albino
And here, the cross between an orange snake and black snake which means:
P0 : ooBB × OObb
offspring of f1 would be =
F1 : OoBb
self cross of f1 offsprings
F2 : OoBb × OoBb
Gametes OB Ob oB ob
OB OOBB OOBb OoBB OoBb
Ob OOBb OObb OoBb Oobb
oB OoBB OoBb ooBB ooBb
ob OoBb Oobb ooBb oobb
here we get approximately similar as Phenotypic ratio as mention in question- 9 : 3 : 3 : 1 or 100:25:22:13
Thus, the correct answer would be: OoBb
Which is the general equation for cellular respiration?
A. carbon dioxide + water + energy --> oxygen + glucose
B. glucose + energy --> carbon dioxide +oxygen + water
C. carbon dioxide + glucose --
--> water + oxygen + energy
D. glucose + oxygen --> water + energy + carbon dioxide
Answer:
D. glucose + oxygen ⇒ water + energy + carbon dioxide
Explanation:
The reactants of cellular respiration, or the substances that are used for the beginning of the chemical process, are sugar (glucose) and oxygen. The products, or the results of cellular respiration, are water, carbon dioxide, and ATP energy. Thus, D is the answer.
The general equation for cellular respiration is glucose + oxygen --> water + energy + carbon dioxide, which is in option D. So, here, the correct answer is option D.
Glucose is a sugar molecule that serves as the primary source of energy for cells. It is derived from the breakdown of carbohydrates in the diet or can be produced through other metabolic processes. Oxygen is required for cellular respiration as the final electron acceptor in the electron transport chain. It is obtained from the air through breathing or from other sources in organisms that do not respire aerobically. During cellular respiration, glucose and oxygen undergo a series of metabolic reactions in different stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation. The correct option is option D.

18) What kind of mutation causes extensive damage in the DNA?
a. Point mutation c. Frame shift mutation b. Chromosomal mutation d.Nonsense mutation
Answer:
c. Frame shift mutation.
Explanation:
Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

Explanation:Confused (NO ANSWER)
They will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).
What is Fertilization in plants?Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.
Steps of Fertilization occur in Plants
1. Pollination
2. Germination
3. Fertilization
Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.
Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).
