A scientist studies how the number of coyotes in San Diego County has changed over the last decade. Is this a population-level study, a community-level study, or an ecosystem-level study?

Answers

Answer 1

Answer:

Population level

Explanation:

Ecological studies can be performed at different hierarchy levels:

Organism Population CommunityEcosystemPopulations are groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring, and living in the same habitat at the same time. These groups are reproductively isolated from other species groups. Individuals belonging to a species cannot reproduce with members of other species.

What results of interest about this organization level is knowing the minimum size of the population needed to leave fertile offspring that ensure the population will survive over time. Genetic variability is also a significant factor because it allows evolutive adaptation to environmental changes. A population might be severely affected by evolutive forces such as genetic flow, genetic drift, and natural selection.

When analyzing the evolution of a population in time, there are parameters to consider regarding its size, such as the generational time, growth rate per capita, the net reproductive rate, the reproductive value, among others.

A community might be defined as a group of organisms of different species that coexist in a specific time and space.

When ecologists talk about a Community, they refer to the existing interaction between different species that share the same habitat and at the same time. What results of interest about the study of this organization level are the inter-specific interactions. These interactions involve competition, predation, parasitism, mutualism, etcetera, and each species carries out a different role in these interactions. These relationships and the results are what determine the destiny of the populations and their size.

The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.  

• Biotic factors are all the living components in the ecosystem.

Biotic and abiotic factors influence the survival and reproduction of living beings. These are constantly interacting. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.

Every abiotic component influence organisms and their survival and reproductive rates.

When analyzing how the number of coyotes in San Diego County has changed over the last decade, we are performing a population-level study. We need to know how the population changed its size through the years, but not the interactions with other species or abiotic factors. Interactions are not of interest in this study.

b. but are reproductively incompatible.
c. whose members have the ability to interbreed and produce viable, fertile offspring.
d. whose members have the ability to interbreed but do not produce viable offspring.

Answers

AnsweR

D.

Explanation:

The biological concept of species states that a species is a group of organisms that can reproduce and produce fertile offspring. This concept was developed by Ernst Mayr.

According to the biological concept of species:

A species is represented by individuals that form a population whose members have the ability to interbreed and produce viable, fertile offspring (Option c).

There are four main types of species concepts: biological, typological, nominalistic and evolutionary Species Concept.

The biological species concept cannot be used in organisms that reproduce asexually.

In conclusion, a species is represented by individuals that form a population whose members have the ability to interbreed and produce viable, fertile offspring (Option c).

Answers

Answer:

Reduced risk of neural tube defects- diet adequate in synthetic form of folate Reduced risk of hypertension and stroke- diet low in sodium and high in potassium Reduced risk of cardiovascular disease- fatty acids from oils present in fish Reduced risk of some types of cancer- diet rich in fiber

Explanation:

As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.

The cell membrane acts as a barrier and protects the cell from foreign substances. It regulates the entry and exit of proteins and compounds by regulating transport.

The correct option is:

Option D. Exocytosis

The cell process can be explained as:

When a solute travels from high to low electrochemical potential is called passive transport.

When a solute moves passively with the help of membrane proteins across the membrane then they are called facilitated diffusion.

When a solvent moves from a region of high to low water concentration is called osmosis.

When secretory vesicles fuse with the plasma membrane and release the content into extracellular cavities is called exocytosis.

Therefore, the process is of exocytosis.

Calico cats have patches of black and orange fur X inactivation X-linked Color blindness is more common in men "Heterozygotes" can express the recessive phenotype Hemophilia Rett syndrome is not always fatal in females Barr bodies

Answers

Answer:

X chromosome inactivation:

- Calico cats have patches of black and orange fur

- "Heterozygotes" can express the recessive phenotype

- Rett syndrome is not always fatal in females  

- Barr bodies

X linked traits:

- Color blindness is more common in men  

- Hemophilia  

Explanation:

X chromosome inactivation refers to the mechanism in which one X chromosome is randomly inactivated during early embryonic development in female mammals. The inactivated (silenced) X chromosome is condensed into a structure called Barr body. In cats, the gene encoding for the orange/non-orange fur coloring is X-linked, thereby X inactivation explains why most calico cats (i.e., those cats that have a color pattern with orange and black spots) are female. Moreover, Rett syndrome is a neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene, and therefore this disorder is much more serious in males. On the other hand, color blindness is more common in men because males have only one X chromosome. In the same way, hemophilia, which is a disorder caused due by a mutation in one gene required for synthesizing one clotting factor, is more common in males than in females because the gene responsible for this disorder is located on the X chromosome.

X chromosome inactivation:

X chromosome inactivation refersto the mechanism wherein one X chromosome is randomly inactivated for the duration of early embryonic improvement in lady mammals. The inactivated (silenced) X chromosome is condensed right into a shape referred to as Barr body. In cats, the gene encoding for the orange/ non-orange fur coloring is X-connected, thereby X inactivation explains why maximum calico cats (i.e., the ones cats which have a colour sample with orange and black spots) are lady. Moreover, Rett syndrome is a neurodevelopmental disease because of a mutation withinside the X-connected MECP2 gene, and consequently this disease is a whole lot greater critical in men. On the alternative hand, colour blindness is greater not unusualplace in guys due to the fact men have handiest one X chromosome.

What us Hemophilia ?

Hemophilia, that is a disease triggered due through a mutation in a single gene required for synthesizing one clotting factor, is greater not in men than in ladies due to the fact the gene accountable for this disease is placed on.e accountable for this disease is placed on.

The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube root of the number of fish. The number of fish in the pond is more than 1 but less than 100. There are no fractional or negative numbers of ducks, fish, or turtles.

Answers

Answer:

There are 64 fish, 8 ducks and 4 turtles.

Explanation:

From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
