what cellular mechanisms allow human body cells to maintain these concentrations ?
Answers
Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.
The sun shining on a tidal pool during a hot day heats the water. As some water evaporates, the pool becomes saltier, causing.
Answers
As water evaporates off salt water, the water gets saltier, and dissolved oxygen in the water reduces.
Dissolved oxygen and solute concentrationThere is an inverse relationship between the dissolved oxygen in water and the concentration of solute.
Thus, as water evaporates off the tidal pool, available free oxygen decreases accordingly just as the water becomes more salty.
In other words, the more water in a solution, the more free oxygen, and vice versa.

Combination of the parents genetics
Explanation:
Every human being has 23 chromosome pairs (not regarding the chromosome pair for the gender). This mean that a human being has 23 chromosomes from their father and 23 chromosomes from their mother and by having those chromosomes in pairs the individual can have both the genetics of the parents and therefore have a mixture of both!

There is no attached photo in this question, however, the question can still be answered. The question also lacks options; they are
A.Comparative B. Descriptive. C. Controlled. D. Experimental
The answer is D. Experimental investigation
Explanation:
There are three types of investigations in science namely: descriptive, comparative, and experimental investigations. Experimental investigations are those investigations that has to do with the testing of how one variable affects another.
In an experimental investigation, a variable called INDEPENDENT VARIABLE is changed to effect a response in another variable called DEPENDENT VARIABLE. In this question, a group of students is testing to see if earthworms prefer rough or smooth surface. Hence, they are testing to see how texture of a surface (rough or smooth), which is the independent variable affects the preference of earthworm. Hence, it is an EXPERIMENTAL VARIABLE.

A human hair cell is unable to transcribe the DNA sequence coding for black hair color. What is one possible effect on the hair produced by this cell?
Answers
Answer:
The hair produced by the cell will not have the BLACK COLORATION
Explanation:
In the process of gene expression, a gene, which is the segment of DNA that encodes useful products, is transcribed into a mRNA molecule. The mRNA is then translated into a protein, which is responsible for the observed traits or characteristics.
In this case, a human hair cell is unable to transcribe the DNA sequence (gene) coding for black hair color (trait). This means that the gene that encodes hair color protein cannot be transcibed, hence, the protein will not be produced in that cell.
If the protein responsible for black hair color is not produced in a cell, the hair produced by such a cell will not be BLACK.

biodiversity?
A. climate change
B. control of pests
C. clean air and water
D. control of soil erosion
Answers
Answer:
C. clean air and water
Explanation:
The reason why this is NOT a benefit of biodiversity is because Plants and Animals really like to mess things up, you know, they really just don't care about what they're destroying, so if there is a crocodile in the water, then it won't care about just playing with some mud, that's why, they make the water dirty, specially while attacking land animals that come to drink the water. Another thing is that they can just p.o.o.p which will not make anything better.
so hence, your answer is C. Clean air and water

Control of pest is not a benefit of Biodiversity. So, the correct option is B.
What is Biodiversity?Biodiversity is defined as the variety of life we would find in an area the diversity of microorganisms such as animals, plants, fungi, and bacteria that make up our natural world. Each of these species and organisms work together in an intricate web-like ecosystem to maintain balance and support life.
Biodiversity or biological diversity is described as the variety and variability of life on Earth as a measure of variation at the genetic, species and ecosystem levels. At the highest level, one can look at all the different species on the entire.

Within a given population of 4000 Vampire bats in Africa, the dominant allele frequency for long ear hairs is .2. What is the frequency of heterozygous bats within the population?
Answers
Based on the data provided, the frequency of heterozygous bats within the population is 0.32
What is the allele frequency?Allele frequency can be defined as the frequency in which a given allele for a gene occurs in a population.
Allele are alternate copies of a gene.
Alleles can be either dominant, recessive or co-dominant.
The allele frequency is given by the Hardy-Weinberg equilibrium equation given below:
p^{2} + 2pq + q^{2} = 1p + q = 1For the vampire bats:
p = 0.2
then; q = 0.8
p^{2} = 0.04
q^{2} = 0.64
The frequency of heterozygous bats within the population = 2pq
2pq = 1 - (0.04 + 0.64)
2pq = 0.32
Therefore, the frequency of heterozygous bats within the population is 0.32

Answer:
1. There is improved medical knowledge which makes people live longer with better medicines.
2. Better standard of living. The middle-class was increasing and people moved to cities. Fewer people starved and more access to technologies.
3. New technologies. Better farm equipment led to more food being produced. With more food, people could live longer.
4. Improved sewer systems/sanitation. Back then people threw their wastes out on the streets. This caused diseases and many children can not make it to adulthood.
5.A better understanding of science and other subjects. Scientists developed vaccines and antibiotics to fight diseases and improve human health.
