1.


A. genetic modification


B. hybridization


C. natural selection

Answer:

1 a 2b 3increase

Explanation:

Genetically fishes have gills to inhale they take water through gills and u know water has some amount of oxygen

Identify what types of of questions that can be answered by science
mamaluj [8]

Answer:

There are many questions that can be answered by science but I will provide some examples below.

Explanation:

Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.

In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:

Biology

Neuroscience (humans)

<em>Is schizophrenia hereditable?</em>

<em />

Behavioral Ecology

<em>Does climate change affect the capability of cuttlefish to camouflage?</em>

Neuroscience (Animals)

<em>Are killer whales capable of  problem-solving?</em>

<em />

Ecology

<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>

<em />

Conservation Biology

<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>

<em />

Animal Behavior

<em>What is the mechanism that Ophiocordyceps unilateralis (Zombie fungus) uses to manipulate ants for its own disperal?</em>

In a population of cats, the phenotypic frequency of black cats is 91%, and the phenotypic frequency of white cats is 9%. Assumi
Talja [164]

Answer:

1. Allele frequency of b = 0.09 (or 9%)

2. Allele frequency of B = 0.91 (0.91%)

3. Genotype frequency of BB = 0.8281 (or 82.81%)

4. Genotype frequency of Bb = 0.1638 (or 16.38%)

Explanation:

Given that:

p = the frequency of the dominant allele (represented here by B)  = 0.91

q = the frequency of the recessive allele (represented here by b)  = 0.09

For a population in genetic equilibrium:

p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)

(p + q)^2 = 1

Therefore:

p^2 + 2pq + q^2 = 1

in which:  

p^2 = frequency of BB (homozygous dominant)

2pq = frequency of Bb (heterozygous)

q^2 = frequency of bb (homozygous recessive)

p^2 = 0.91^2 = 0.8281

2pq = 2(0.91)(0.9) = 0.1638

Explain the different levels of cellular organization.
JulijaS [17]

There are 5 different levels of cellular organization.

Cells, tissues, organs, organ systems and whole organisms. Cells hold genetic material and absorb outside energy.

Tissues make up the bones, nerves and connective fibers of the body. Organs work to perform specific bodily tasks, such as filtering blood. Organ systems are groups of organs that perform a specific kind of function together, such as digesting food.

Together, these smaller systems make up an entire living organism which can grow and then go onto reproduce.
