The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.
The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.
Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.
So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.

a. upwelling along coasts
b. in the middle of the current gyres
c. along the Equator
d. around Antarctica in the summer
e. coasts
Answers
Answer:
Option B, in the middle of the current gyres
Explanation:
The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.
Hence, option B is correct
how does Sexual reproduction leads to genetic variation.
Answers
Answer:
Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Sexual reproduction involves meiosis, which is the process of a cell doubling its DNA, shuffling its genes, and then dividing the shuffled DNA among four cells.
• random fusion of gametes
• random assortment of chromosomes
• Gametes of each parent are a result of meiosis meaning gametes are genetically different so when they fuse together they form a new combination of genes in the zygote

This paramecium has a nucleus and is comprised of one cell. Which terms best describe this organism?
Answers
Answer: The term that best describes this organism is that it's a UNICELLULAR PROTISTA.
Explanation:
Unicellular organisms are that are made up of just one cell. They are also called single- celled organisms. Examples of unicellular organisms include: Amoeba, chlamydomonas and paramecium.
The paramecium is a protist which is SINGLE-CELLED and is made up of eucaryotic cells in which the cell structure is complex with a well-defined NUCLEUS.
The structure of this organism helps it to survive in its environment. It has cilia that helps it move food into its gullet.
The food vacuole circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body. The food vacuoles circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body.
The NUCLEUS is used by the organism for sexual reproduction. This occurs in a process known as conjugation whereby the whole organism pair with another similar whole organism and exchange their nuclei.

What are Adaptation?The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.
The biological process through which organisms adapt to brand-new surroundings or alterations in their current environments is known as adaptation.
Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.
Therefore, Animals are less likely to eat the plant and It tastes bad so they wont want to eat it again.

Part C Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are 1.2.luciferin+O2ATP⇌⇌oxyluciferin+lightAMP+PPiΔG∘=−31.6 kJ/mol If the overall ΔG∘ of the coupled reaction is -4.80 kJ/mol , what is the equilibrium constant, K, of the first reaction at 6 ∘C ?
Answers
Answer:
K = 9.620 × 10⁻⁶
Explanation:
From the given information:
Temperature T= 6° C
= (273 + 6)K
= 279 K
The correct and well presentation of the reactions are:
1. [tex]Luciferin + O_2[/tex] ⇆ oxyluciferin + light ΔG₁°
2. ATP ⇄ AMP + PP[tex]_i[/tex] ΔG₂° = -31.6 kJ/mol
The overall ΔG° = -4.80 kJ/mol
Let's first determine the ΔG₁° for the equation (1)
ΔG° = ΔG₁° + ΔG₂°
- ΔG₁° = - ΔG° + ΔG₂°
ΔG₁° = ΔG° - ΔG₂°
ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol
ΔG₁° = 26.8 kJ/mol
Using the formula:
ΔG° = -RTIn K
[tex]In \ K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}[/tex]
[tex]log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \ K =- 5.017[/tex]
K = antilog (-5.017)
K = 9.620 × 10⁻⁶

Among Delta-back stripped fish, there are two genes that segregate independently of one another. Suppose the alleles at the first locus are A (dominant) and a (recessive) and the alleles at the second locus are B (dominant) and b recessive). If an AABB fish mates with an aabb fish, and their offspring are inter-crossed, the proportion of F2 fish that show a recessive phenotype at the first locus and a dominant phenotype at the second is:
Answers
Answer:
4/16
Explanation:
It is given that the alleles of the first locus = A dominant and recessive a
The allele of the second locus = B dominant and the recessive b.
Now if fish with AABB mates with the aabb fishes, then to tell the proportion of the F2 fish which shows either the dominant phenotype at the [tex]$\text{first locus}$[/tex] and also a recessive phenotype at the [tex]$\text{second locus}$[/tex].
So for this, the recessive phenotype at the [tex]$\text{first locus}$[/tex] as well as the recessive phenotype at the [tex]$\text{second locus}$[/tex] is in the ratio of 4/16.
