Answer:
When a population size reaches the carrying capacity of its environment, the population growth slows down or stops completely.
Explanation:
This is true for the S-curve, but not the J-curve
The logistic growth model depicts the carrying capacity at its maximum level. It is best described as " a population size reaches the carrying capacity of its environment, the population growth slows down or stops completely."
What is logistic growth?Logistic growth has been defined by the growth of the population in ana areas that have to reach their carrying capacity. The growth curve has been limited by food and water resources (environmental factors).
Unlike the exponential curve model, it is an S-shaped model that increases first and then shows a slower growth rate and eventually termination of the population growth due to mortality and natality rate.
It is also called sigmoidal growth where the population size shows an increase at first till the population stabilizes. It is not the same for the J curve as the population does not slow down at the carrying capacity.
Therefore, the affirmation of the slow population size at the carrying capacity is true for the logistical curve (S-shaped) but not for the J-curved model.

Which of the following would provide the best assessment of the parent material of the soil
- O horizon
- A horizon
- B horizon
- D horizon
Answer:
The correct answer is B
Explanation:
It may be made of the same mineral material that the more superficial layers were formed from, or it may be made of a distinct complex of minerals, rock forms the D horizon, hence option D is correct.
What is the parent material of the soil?An unweathered soil layer that can occasionally be found below the B-horizon or the C-horizon, if they are present.
The soil you see above this rock is made of rock that has weathered (unless the soil has been deposited from elsewhere eg floodplains contain soil that has been carried downstream in water and then deposited as the flood recedes).
Therefore, bedrock's D Horizon - Rock that has been solidified makes up this stratum (tight, unbroken, large formations of rock). Roots do not penetrate thus far down, and there is very little organic matter.

Which three organs help a plant carry out photosynthesis?
Answer: B, C, and D.
Explanation: Leaves absorb the light coming from the sun. Leaves also have something included in them called chlorophyll. Plants use this chlorophyll and light for photosynthesis. The stem helps to transport the products of photosynthesis. The roots absorb some of the most important nutrients to a plant.
Three organs that help a plant carry out photosynthesis are the leaves, by trap sunlight and take in carbon dioxide, and the stem, which transports nutrients and water to plant cells.
What is photosynthesis?Photosynthesis is a chemical process by organisms that contain chlorophyll to make their own food. The process includes light, carbon dioxide, water, and chlorophyll.
Thus, the correct options are B and C.

4. Bacteria can share genetic information with each other. How does this make it more difficult to design medications that attack bacterial colonies? (4 points)
Explanation:
Genetic exchanges among bacteria occur by several mechanisms. In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.
Genetic information in bacteria and many viruses is encoded in DNA, but some viruses use RNA. Replication of the genome is essential for inheritance of genetically determined traits. Gene expression usually involves transcription of DNA into messenger RNA and translation of mRNA into protein.
Answer:
The bacteria shares information with the recipient, making it harder to differentiate between the bacteria, and the host.
Explanation:
It mates with the recipient's cells and transfers genetic information. Since bacteria is living, it can share this to the host, making it less recognizable. This would make it more difficult to target only the bacteria.

In a species of bird, the allele for the striped trait is recessive to the allele for the speckled trait. Suppose that a coastal bird population has a striped phenotype frequency of and an inland population has a striped phenotype frequency of The two populations are isolated and in Hardy–Weinberg equilibrium. Let represent the allele frequency of the coastal population and represent the allele frequency of the inland population. Calculate the allele frequency for the striped allele for each population. Round your answers to the nearest hundredth.
Answer:
The answer is "0.42"
Explanation:
Please find the complete question in the attached file.
Coastal community striped allele intensity [tex]= q = 0.62[/tex]
Landlocked community, strip intensity allele[tex]=q'=0.40[/tex]
Its eliminated allele frequency for movement [tex]= q"=0.42 \ in \ indoors[/tex]community And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts[tex]=q_2=0.39[/tex]
Heritable (striped) allele frecency:
[tex]\to q=\sqrt{q_2}[/tex]
[tex]=\sqrt{0.39} \\\\ =0.624 \\\\ =0.62[/tex]
(round up to the closest cent) is therefore the only frequency of coastal people.
The genome of pulling function in host population[tex]= q'_2=0.16[/tex] Heterozygous feature regularly.
Therefore the inland community rate of recessed (striped), allele rate:
[tex]\to q'= \sqrt{q'_{2}}= \sqrt{0.16}=0.40[/tex]
Following migration;
Its percentage of coastal migrants:
[tex]m=10\% \\\\[/tex]
[tex]= \frac{10}{100} \\\\= 0.1[/tex]
Coastal population Non-immigrant percentage of coastal residents:
[tex]=1- m\\\\=1-0.1\\\\ =0.9[/tex]
Stripping coastal community of allele rate after immigration:
[tex](q")=\text{(stripping of migrant only freq)}\times (m)+\text{(stripping allele baud rate for non-immigrants)} \times ( 1-m)[/tex]
[tex]= [q \times m]+[[q' \times(1-m)]\\\\=(0.62 \times 0.1)+(0.40 \times 0.9)\\\\=0.062+ 0.36\\\\=0.422\\\\=0.42[/tex]

Which best describes the law of independent assortment?
A. Traits can only be controlled by a single gene.
B. The traits of the F2 generation are random.
C. The traits of an offspring are independent from the parents.
D. When sex cells form, alleles of a trait separate independently.
Answer:
D. When sex cells form, alleles of a trait separate independently.
Explanation:
i got it right on the test
According to the law of independent assortment, during the formation of gametes, the separation of traits occurs independently. So option D is correct.
Segregation is the principle that each individual has two alleles, and only one of those alleles is inherited by the progeny. Independent assortment is the principle that the genetic makeup of one pair is independent of the genetic makeup of another pair.
Each gene comes in different versions, called alleles. The dominant allele hides the recessive allele, which determines the appearance of the organism. When an organism creates gametes, only one gene copy is selected at a time. This is called the law of segregation.
