Answer:the answers are a and d
Explanation:
I did the test sorry if wrong
In the given image, it is showing that plants use carbon dioxide gas to make sugars during photosynthesis. The correct option is D.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the ambience into Earth's living organisms and then back into the atmosphere. The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, environment, and living organisms.
Plants consume carbon dioxide and sunshine during photosynthesis to produce fuel i.e., glucose and other sugars for the construction of plant structures. The fast biological carbon cycle is built on this process.
Thus, the correct option is D.

An endotherm is an organism that uses internal body heat to maintain a metabolically suitable temperature rather than relying on ambient heat. The endotherms primarily include the birds and mammals.
Why are birds and mammals endotherm?In contrast to organisms that rely on the heat of their surroundings to sustain a temperature that is optimal for their metabolic processes, endotherms generate their own heat from within their bodies. The majority of endotherms are comprised of different kinds of birds and animals.
Endotherms, which include birds and mammals, generate and store a significant amount of heat within their own tissues, as opposed to ectotherms, which include insects and reptiles, who take in heat from their surroundings. Insects and reptiles are examples of ectotherms.

A 200g ball begins falling from a height of 15m. If the (a) acceleration due to gravity is 10 m/s^2. How long do you calculate it will be before the object reaches the ground? Which formula will you use?
Answer:
1.732 seconds
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Explanation:
s = Displacement of ball = 15 m
g = a = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
u = Initial velocity of the ball = 0
t = Time taken
From the kinematic equations we use the following formula
[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow 15=0t+\dfrac{1}{2}\times 10t^2\\\Rightarrow t=\sqrt{\dfrac{15\times 2}{10}}\\\Rightarrow t=\sqrt{3}=1.732\ \text{s}[/tex]
The object will reach the ground after 1.732 seconds.
The formula used is [tex]s=ut+\dfrac{1}{2}at^2[/tex].

What conditions make for a violent volcanic eruption?
OA. Magma with low gas content
OB. Magma with low viscosity
OC. Magma with high silica content
OD. Magma that can flow easily
Answer: B
Explanation:
Magma with low viscosity
Magma that has high content of silica will lead to a violent volcanic eruption. Thus, the correct answer is option C.
What kind of magma results in violent volcanic eruption?Magma that has a high content of silica will have high viscosity. This is due to the bond formation between silicon and oxygen, forming a Si-O tetrahedron.
These tetrahedra combine with each other and result in polymerization which increases the resistance of the liquid to flow. This type of thick magma does not flow easily and will result in an explosive eruption.
High amount of silica causes a lot of gas to be trapped in the volcano. High-viscosity magma does not allow for the exsolution of gas bubbles.
Thus, the gas bubbles will be trapped inside and increase pressure on the magma column to explode. The trapped gas thus provides the driving force for the explosion.
Thus, the correct answer is option C.

These are called multiallelic traits. If GGHHII was crossed with gghhii, what would the genotype for every offspring be?
a. ggGGhhHHIIii
b. GGhHII
c. GgHhIi
d. ggHHii
Answer:
In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).
Explanation:
The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.
This can be tested by making a Punnett square for this cross:
GGHHII X gghhii
Alleles GHI GHI
ghi GgHhIi GgHhIi
ghi GgHhIi GgHhIi
Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi

Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
What are cells?Cells are the fundamental building blocks of all life. Trillions of cells make up the organisms' body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic molecules found in all cells.
Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
Like the walls of a house, all cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell's internal and external environments.
