Why do animals such as sparrows and deer experience less loss of genetic diversity due to fragmentation than for instance mice or salamanders

Answers

Answer 1

Answer:

Severe fragmentation is a typical fate of native remnant habitats in cities, and urban wildlife with limited dispersal ability are predicted to lose genetic variation in isolated urban patches. However, little information exists on the characteristics of urban green spaces required to conserve genetic variation. In this study, we examine whether isolation in New York City (NYC) parks results in genetic bottlenecks in white-footed mice (Peromyscus leucopus), and test the hypotheses that park size and time since isolation are associated with genetic variability using nonlinear regression and information-theoretic model selection. White-footed mice have previously been documented to exhibit male-biased dispersal, which may create disparities in genetic variation between males and females in urban parks. We use genotypes of 18 neutral microsatellite data and four different statistical tests to assess this prediction.

Which of these organisms would most likely live in a intertidal zone?

D. Venus fly-trap

Answers

Answer:

a algae

Explanation:

it lives there in the ocean

Of these organisms, algae would most likely live in a intertidal zone.

How does algae survive in intertidal zone?Any organism that lives in the intertidal zone must be able to tolerate powerful waves and variations in moisture, temperature, and salt. Sea stars, snails, seaweed, algae, and crabs can be found in the intertidal areas of rocky shorelines. Many brown algae in the intertidal zone have alginic acid in their cell walls, which acts as a water-absorbing gel and prevents the algae from drying up during low tides. In environments with high nitrogen levels, intertidal macroalgae can also outgrow seagrasses. In certain situations, certain algae can be a nuisance. The blue-green algae, also known as cyanobacteria, are ephemeral in their growth and recurrence. They can form mats or filaments and are encrusting.

Support the following claim: All primates have a common ancestor. use multiple lines of evidence (anatomical, DNA, and embryological evidence) to support the claim. compare the value of each type of evidence, and explain which type of evidence is most valuable for determining evolutionary relationships.

Answers

Evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.

What are primates?

Primates are mammals which belong to the order primates.

Primates have unique features such as:

prehensile five-digit hands and feetpossession of flat nails instead of claws acute vision with depth perception due to forward-facing eyes

Primates include man, monkeys, chimpanzee, etc.

The primates share a common ancestor as their anatomical structure are similar with hands and feet.

Embryologically, they are similar too and they share over 90% of their DNA in common.

Based on value, the DNA evidence is the most supportive of common ancestors as the DNA determines the other features of the primates.

Therefore, evidence such as similarity in DNA make-up, embryological and anatomical similarity shows that primates share a common ancestor.

Describe one way that burning rain forest trees affects nutrient cycling differently than cutting them down and leaving them on the forest floor.

Answers

Answer is : Burning tree releases CO2 waste into atmosphere, cutting down trees down allows the nutrients to return to the ground.

Give me a brilliant if I deserve it :)

Burning trees releases co₂ in the atmosphere, but cutting down trees falling on the ground nutrient returns to the land. Plants which is falling down decomposes and nutrient return to the soil.

How do trees affect the nutrient cycle?

Deforestation affects the nutrient cycle because plants are the storage site of many nutrients. The nutrient cycle is interconnected with plants most of the nutrient is directly absorbed by the soil.

Plants absorb nutrients from the soil, and the animal takes nutrients from the plants, when an animal dies its body decomposes in the soil again nutrient dissolve in the soil.

Burning plants releases stores of nitrogen, carbon, and sulfur these create a loss in biodiversity and affect the nutrient cycle.

Therefore burning rainforest affects the nutrient cycle by releasing nutrient components in the atmosphere, so cutting down does not affect

In Point A, with regard to the population and resources available at that point in time, the populace has access to ample resources.

What is a population?

The term “population” refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.

Growth rates are the population changes that occur each year as a result of births, deaths, and net migration. The resources and the population are stable, but as the population grows, fewer resources will be available.

Populations can include but are not limited to, individuals, animals, organizations, structures, buildings, cars, farms, objects, or occasions.

Therefore, in Point A, the population has access to enough resources given the population and resources available at that time.

The metaphase stage of meiosis is the stage where the chromosomes/chromatids align at the center or equator of the cell in preparation for separation.

However, in metaphase I, homologous chromosomes are aligned at the center of the cell.

Each homologous chromosome face opposite spindle poles during this stage.
