Provide one biotic factor that could increase the deer population's carrying capacity. Explain why this biotic factor would increase the carrying capacity.

Answers

One biotic factor that could increase the deer population's carrying capacity is the availability of food. If there is an abundance of food, such as vegetation and plant matter, then deer will have an easier time finding enough food to survive and reproduce. This can lead to higher birth rates and better overall health for the population, which can increase the carrying capacity. Additionally, if there is more food available, it can also attract more deer to the area, further increasing the population size that can be supported by the available resources.

Wildlife management Damage from the choices presented below. fox killing a rabbit


A raccoon eating three ears of corn


A coyote eating neighborhood house cats


A muskrat in an urban window

Answers

Wildlife management typically involves finding ways to strike a balance between the needs and behaviors of wild animals and human activities. In the examples you provided:

What is wildlife management?

Fox killing a rabbit: This is a natural and normal behavior for foxes, and they are important predators in many ecosystems. In most cases, it is not necessary or desirable to intervene in these interactions. However, if there are concerns about the overpopulation of rabbits or other ecological factors, a wildlife biologist or other expert may be consulted to assess the situation and recommend appropriate management strategies.

Raccoon eating three ears of corn: Raccoons are opportunistic feeders and will eat a wide variety of foods, including crops like corn. If the damage is minimal, it may be sufficient to simply tolerate the presence of raccoons and take steps to prevent future damage (such as securing the corn or using deterrents). In cases where the damage is severe or persistent, other strategies such as trapping or relocation may be necessary. However, it is important to note that these methods can be controversial and should only be carried out by licensed professionals.

Coyote-eating neighborhood house cats: Coyotes are native predators that play an important role in many ecosystems. However, conflicts can arise when they prey on pets or livestock. To reduce these conflicts, it is important to keep pets indoors or supervised when outside, and to remove attractants such as garbage or pet food. In some cases, it may be necessary to remove individual problem coyotes or implement other management strategies.

Muskrat in an urban window: Muskrats are semi-aquatic rodents that are adapted to wetland habitats. Finding one in an urban area is unusual, and may indicate that the animal is lost or displaced. In this case, the best approach would be to contact a local wildlife rehabilitator or animal control agency to assess the situation and determine the most appropriate course of action. It is important to handle wild animals with care and to avoid touching or approaching them, as they can carry diseases and may become aggressive if frightened or cornered.

Explain why every cell that is produced from the genetically modified bacterium
will be able to produce insulin.

Answers

Answer:

Recombinant DNA is technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory. Then they remove a loop of bacterial DNA known as a plasmid and insert the human insulin gene into the plasmid. Researchers return the plasmid to the bacteria and put the “recombinant” bacteria in large fermentation tanks. There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria and purify the substance for use as a medicine for people.

Factors affecting energy transfer SELLECT ALL THAT APPLY


Lesson 2. 14





Question 9 options:



Wind moving over a relatively FLAT water surface has GREATER area to come in contact with the water, and this INCREASES energy transfer.




SMALLER waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.




Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.




Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer

Answers

Factors affecting energy transfer include the area of contact between wind and water, as well as wave size.

The surface area of the water that the wind comes into contact with can impact energy transfer. A relatively flat water surface provides greater area for the wind to come in contact with, which increases energy transfer.

Additionally, the size of waves can also impact energy transfer. Smaller waves have more space and areas to trap air, which increases energy transfer.

On the other hand, larger waves also have more spaces and areas to trap air, which also increases energy transfer.

Therefore, both wave size and surface area of contact between wind and water are important factors to consider when analyzing energy transfer.

Which of the following best describes the relationship between the endoplasmic reticulum and the plasma membrane in eukaryotic cells?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, there is a distinct relationship between the endoplasmic reticulum and the plasma membrane. The endoplasmic reticulum are responsible for protein synthesis which are used by the remaining organelles (including the membrane) to function. The endoplasmic reticulum is also involved in lipid synthesis and has a network of tubules (which are used for carrying materials throughout the cell) that can deliver lipids into the cell membrane. These lipids are responsible for the semi-permeability function of the cell/plasma membrane.

Your colleague has collected some sediments from a mangrove swamp and then grows the bacteria from those sediments on an agar plate to determine the concentration of bacteria in those sediments.

a) Describe why the resulting bacterial concentration is an underestimate of the actual concentration of bacteria in those sediments.

b) State what method they should have used instead to more accurately determine the bacterial concentration.

Answers

From the question;

1) It may have been underestimated sue to visibility bias

2)  The method of direct microscopic count or direct cell count can be employed.

What about the bacteria?

On the particular agar medium employed, not all bacteria contained in the sediments may be viable or able to grow. Some bacteria might no longer be culturable or in a dormant state, which limits their capacity to grow into colonies on the agar plate. This viability bias may lead to the underestimate of the bacterial population by excluding a sizable fraction of it.

A direct microscopic count entails using a microscope to directly observe and count bacterial cells. Without the bias imposed by culture-based approaches, it provides a more thorough count of bacterial cells, including viable and non-viable cells.

(Choose the most accurate term.) infected parasitized infiltrated colonized contaminated

Answers

Answer:

contaminated

Explanation:

The gut microbiome has a fundamental role during the first years of life. Newborns 'contaminate' with microbes from contact with family members, and, subsequently, these microorganisms act to colonize their gut microbiome. Metagenomics analyses showed that microbiome diversity may be very high among infants and early microbial colonization has been shown to be critical during this process. The gut microbiota has critical functions which include, among others, nutrient homeostasis, mineral absorption, enzymatic activity, synthesis of amino acids, etc. It has been reported that early microbial colonization can even modulate target gene expression through the alteration of epigenetic marks (i.e., differential DNA methylation patterns).

Where is most of the baryonic matter (ordinary matter) of the universe found?

A. in planets and natural satellites
B. in comets and asteroids
C. in dark matter and dark energy
D. in interstellar gases and stars

Answers

Baryonic dark matter may occur in non-luminous gas or in Massive Astrophysical Compact Halo Objects, and stars. So therefore it’s D.

Most of the baryonic matter (ordinary matter) of the universe is interstellar gases and stars. Baryonic matter is the visible matter. Thus, the correct answer is D.

What is Baryonic matter?

Visible matter is also known as the baryonic matter. It consists of baryons which are subatomic particles such as protons, neutrons and electrons.

In cosmology, baryonic dark matter is the dark matter composed of baryons. Only a small proportion of the dark matter in the universe is likely to be baryonic the rest of the matter is all dark matter. Baryonic matter only includes matter composed of baryons.  It can be described as the baryons are made up of protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude other things like electrons and neutrinos.

Therefore, the correct answer is D.

Answers

The proper order of cellular respiration from start to end is:

1. Transport of glucose into cell
2. Glycolysis
3. Pyruvate Transition step
4. Citric Acid Cycle
5. Electron Transport Chain

During glycolysis, glucose is broken down into pyruvate molecules, which then enter the pyruvate transition step where they are further broken down into Acetyl-CoA. The Acetyl-CoA then enters the Citric Acid Cycle, where it is fully oxidized and produces ATP, NADH, and FADH2. These energy-rich molecules then enter the Electron Transport Chain, where they are used to generate ATP through oxidative phosphorylation.

According to Darwin’s theory of evolution all species on earth are united by?

Answers

Answer:
A universal common ancestor (UCA).

Explanation:
According to Darwin, all life on Earth evolved from a universal common ancestor; that is, the very first organism on Earth. If you pick any living plant or animal on Earth and trace its lineage back far enough, billions of years ago, you will eventually find the UCA. Every species on Earth is united to every other species through their connection with the UCA.

The UCA itself was probably a single-celled organism of some kind and died about 4.1 billion years ago. But through it, every species, be it human, dog, tree, or mushroom, shares this one ancestor with everyone else.

Species also have what's called a lowest common ancestor with each other, much more recent than the UCA. For example, the LCA between humans and chimpanzees probably lived and died around 4 million years ago.
