This summer, you are returning to the research station in Costa Rica to follow up on the population of butterflies you have been studying. You are disappointed to find that there are fewer this year than last. In fact, at dinner your friends studying frogs and birds are complaining about the same thing. What type of influence do you suspect

Answers

Answer 1

Answer:

it is likely that there was an environmental disturbance that affected the population density of the species.

Explanation:

All animals have their survival and reproduction capacity directly linked to environmental quality. This is because these animals take from the environment all the resources needed to live and develop. In this case, when the environment is balanced and has the necessary resources for life, animals can survive longer and develop well, being able to reproduce, generating more animals that increase the population density of their species. However, when this environment is disturbed, the animals' survival is threatened, even failing to reproduce. This lowers population density.

In the case presented in the question above, it is likely that populations of butterflies, frogs and birds are decreasing due to environmental disturbances.

In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.

Answers

Answer:

If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes

Explanation:

Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.

Answers

Answer:

The correct answer is - mitochondria lack ribosomes like prokaryotes.

Explanation:

The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.

This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.

How do white blood cells protect the body against infections

Answers

Answer:

White blood cells, which are also called leukocytes or white corpuscles, are a cellular blood component that does not include hemoglobin, have a nucleus, are motile, and protect the body from infections and diseases through ingestion of foreign materials and cellular debris, destruction of infectious agents and cancer cells or production of antimicrobials.

Explanation:

There are 4,500 to 11,000 cells in the white blood of a healthy adult person per cubic mm of blood. During the day, fluctuations in the number of white cells take place; lower values during rest and higher during exercise are attained. The quantity of white cells increases abnormally, while the number decreases abnormally, Leukopenia.

Intensive physical activity, seizures, extreme emotional response, pain, pregnancy, labor, and specific conditions such as infections and intoxications may increase the counting of white cells. In reaction to some types of infections or medication, or in conjunction with certain illnesses such as chronic anemia, malnutrition, or allergy, the number may drop.

Answers

Answer:

B. The sun's rays strike the water at an angle at the poles.

Answer:

b

Explanation:

At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles

Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?

Answers

Answer:

A

Explanation:

All mating must be totally random

Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.

What are the requirements of the law ?

In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.

Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.

Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.

Answers

Answer: 7.5  grams per cubic centimeter.

Explanation:

We area given that , Mass of something is 12 grams

Volume of that thing is 1.6 cubic centimeters

To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)

Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]

Number of gram per cubic centimeters = 7.5

Therefore, 7.5  grams per cubic centimeter. (density of the thing)
