What are the effects of the mass extinction of permian on marine organisms and insects.
Answer:
At the end of the Permian, conditions became unsuitable for most life and about 95% of marine species were eliminated as well as 70% of terrestrial species in a very short period of time, in geologic terms. It was also one of the few known mass extinctions of insects. Many plant species also went extinct.List two characteristics of igneous rocks that make them good

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?
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

Why do offspring produced sexually look similar to their
parents but not identical?
Answer:
In the process of sexual reproduction, haploid gametes produced by the meiotic division fuses to form a diploid zygote. A child inherits half of the genetic material from each parent. So, it may be they look alike but they are not identical to their parents.
Explanation:
I'm not an expert tho so if I'm wrong then dang
Answer:
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!

The sun shining on a tidal pool during a hot day heats the water. As some water evaporates, the pool becomes saltier, causing.
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.

Which of these changes to the cell would cause the greatest reduction in the activity of catalase? A. A decrease in the concentration of hydrogen and oxygen B. An increase in the concentration of hydrogen peroxide C. A strong bonds between carbon atoms that cannot be broken D. Ionic bonds between carbon atoms and oxygen atoms
Answer:
A. A decrease in the concentration of hydrogen and oxygen
Explanation:
Catalase's function is to catalyze the decomposition of hydrogen peroxide (H₂O₂), which is a toxic substance for cells, into oxygen (O) and water (H₂O).
The following chemical reaction can represent the catalase enzymatic action:
2H₂O₂ + Catalase → H₂O + O₂
Due to this, as oxygen and hydrogen (H) are structurally essential for the catalase reaction, the decrease in the concentrations of these substances would also reduce the enzyme's action potential.

Which is NOT a
benefit of
biodiversity?
A. climate change
B. control of pests
C. clean air and water
D. control of soil erosion
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

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.
Answer:
The answer is Comparative
