What is the second most abundant element on earth and seems to be very important in biological processes such as oxygen transportation in the body and cellular respiration
Answer:
iron
Explanation:
Cellular respiration may be defined as the group of metabolic processes as well as reactions which occurs in the cells of the organisms that converts the chemical energy from the oxygen molecules or from nutrients into ATP or adenosine triphosphate and then releases the waste products. Thus it breaks the glucose and produces the ATP. Iron is an important element which are used in many important biological processes in the body like the cellular respiration and oxygen transportation.

Arenite can be defined as the sedimentary clastic rock.
It is of the sand grain size.
It also comprises of matrix.
It is a metamorphosed sediment.
Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.
What does the slope of the curve on a distance vs time graph represent?
Answer:
What does the slope represent on a velocity graph? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

In cats, short hair (H) is dominant to long hair (h).
Using the punnett square above, what is the probability the offspring from this cross
would have long hair (hh)?
0/4
O 1/4
2/4
Answer:
0/4
Explanation:
All offspring will have the presence of the dominant trait in their genes, which will make them have short hair.
They will all have the geneotype Hh.
They would need hh to have long hair.

Which of the following has the greatest effect
on soil's capacity to retain water?
A Soil color
B Soil particle size
C Soil texture
D Soil fragrance
The water-holding capacity of a soil is the the amount of water that a given soil can hold for plants to utilize
The soil particle size has the greatest effect on soil's capacity to retain water.
Soil particle size and organic matter (the soil's composition) are main determinants of water-holding capacity of a soil. Smaller particles (silt and clay) have a bigger surface area than larger sand particles, allowing the soil to hold more water.Learn more about the water holding capacity of soil: https://brainly.com/question/8464940
Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
O Most countries have laws against it, so the impacts have not been tested.
Answer:
I'm pretty sure its...
Explanation:
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.
what is deep sea mining?The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.
The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.
Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.
There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.
This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.
Hence , the correct option is A.

This substitution score matrix called _____ is derived from protein families that are characterized by blocks of conserved amino acid sequences.
Answer:
BLOSUM
Explanation:
A substitution matrix is a matrix used in bioinformatics (and also in computational biology) to determine/estimate the rate at which one character -which is specified by a nucleotide sequence in nucleic acid alignments or by one amino acid in protein alignments-, changed to another character during the course of the evolution. The BLOcks SUbstitution Matrix (popularly known as BLOSUM) is a substitution matrix used to score one amino acid for another in a protein alignment. The BLOSUM substitution matrix is particularly useful to compare evolutionarily conserved regions between protein sequences and thus score their alignments, where each entry is indicated by a similarity score between two amino acids.
