Explanation:
sorry if that didn't help
A pond has fish, crawfish, oysters, lilies, and algae. All these species represent the pond's ecosystem.
What is an ecosystem?All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue.
Producers, consumers, and decomposers are the three groups of living things that make up an ecosystem. Each of them contributes significantly to the ecosystem. Forest, desert, rainforest, grassland, tundra, savanna, and mountain habitats are the main categories of ecosystems.
Hence, a pond has fish, crawfish, oysters, lilies, and algae. All these species represent the pond's ecosystem.

Rainbows, like the one shown below, form when sunlight passes through raindrops and is separated into different colors.
What happens to the sunlight when it passes through the raindrops that causes the rainbow to form?
A.
The sunlight travels in a straight line through the raindrops.
B. The sunlight is absorbed by the raindrops.
OC.
The sunlight is reflected off of the raindrops.
D.
The sunlight is bent and redirected by the raindrops.
Answer:
D. The sunlight is bent and redirected by the raindrops
Explanation:
This is refraction of light.Understand clearly the difference between reflection which is the bouncing back of light on shiny smooth surfaces and refraction is the bending of light therefore when the sun rays hit the raindrops it is bent and the light is split from a white colour to seven colours known as spectrum

The hormones of the adrenal medulla are modified
(a) fatty acids. (b) amino acids. (c) monosaccharides. (d) nucleotides. (e) steroids.
Answer:
b
Explanation:
hormones of adrenal medulla are Adrenaline and non- Adrenaline. they are the derivatives of amino acids called Tyrosine( aromatic Amino acid)
The hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.
What is the Adrenal medulla?The adrenal medulla may be defined as an internal part or region of the adrenal gland which is located at the region of the top of each kidney.
The adrenal gland is a small gland that comprises the adrenal cortex and adrenal medulla. The adrenal cortex synthesizes steroids hormones like mineralocorticoids, glucocorticoids, etc. While the adrenal medulla is responsible for the secretion of epinephrine and norepinephrine.
The hormone epinephrine is also known as adrenaline. It is often called catecholamine. This epinephrine is extracted from the derivatives of amino acids known as tyrosine.
Therefore, the hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?
(A) A small population size
(B) A highly diversified gene pool
(C) specialized cells within the body
(D) Many individuals with the recessive trait
A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.
