A. Population growth is decreasing
-2
+4
-10
-3
-8
-3

So the population decreased by 24 because 3+3+8+10+2=26-2=24.

Hoped I helped!
Answer 2

There are different aspects to population. The option that describes what is occurring in the population of squirrels is that Population growth is decreasing.

When you study the population, you will see that it decreased by 24.

That is; 3+3+8+10+2=26-2=24.

What factors affects squirrel populations?

The Natural populations theory is one that states that an organism must live within some specific limits. Squirrels cannot live in places that  gets too hot or too cold,

Physical factors such as temperature, water availability, mineral nutrients are known to be factors that reduces where these species lives.

The mpf protein complex turns itself off by _____.

Answers

Final answer:

The MPF protein complex turns itself off by the targeted degradation of its cyclin subunit towards the end of mitosis, allowing the cell to progress to the next stage of the cell cycle.

Explanation:

The MPF protein complex turns itself off by initiating the degradation of its cyclin subunit. MPF, also known as Mitosis Promoting Factor, is composed of two subunits: cyclin and cyclin-dependent kinase (cdk). While levels of cdk remain relatively constant, the levels of cyclin vary, accumulating during the G₁ phase and peaking at mitosis before they are targeted for degradation. This degradation process involves proteasomes that break down cyclin, leading to the inactivation of MPF towards the end of mitosis. The breaking down of cyclin is a critical step in ensuring that MPF activity ceases, allowing the cell to exit mitosis and enter the G₁ phase of the cell cycle.

How does the serratus anterior function as an antagonist to the rhomboid muscles?

Answers

Answer: Serratus anterior abducts the scapula and rhomboids adducts the scapula.

Serratus anterior is a muscle that originates  of the 1st to 8th ribs at the side of the thorax and inserts in the medial border of the scapula. This muscle during contraction abducts the scapula and the rhomboids muscles do the opposite by retracting the scapula toward the vertebral column(adducts).




Final answer:

The serratus anterior functions as an antagonist to the rhomboid muscles by performing protraction of the scapula, which is the opposite action of the rhomboids' retraction of the scapula.

Explanation:

The serratus anterior is a large and flat muscle that originates on the ribs and inserts onto the medial border of the scapula. Its primary function is to pull the scapula forward and around the rib cage, a motion known as protraction. This movement is opposite to that of the rhomboid muscles, which retract the scapula by pulling it towards the vertebral column.

Antagonistic muscles have opposite actions. When the serratus anterior contracts, it works against the rhomboids. If the rhomboids are contracting to bring the scapula medially (retraction), the serratus anterior will be relaxed. Conversely, when the serratus anterior contracts to move the scapula laterally (protraction), the rhomboids will be relaxed. This opposition is what makes the serratus anterior an antagonist to the rhomboids.

As we try to fight it with more antibiotics, it may become immune to those as well, eventually creating a bacteria immune to most antibiotics, leaving us unable to fight it, especially in poorer areas, due to the fact that if we did create new antibiotics they would be more expensive than your common antibiotic, such as penicillin.

The membranes of neurons at rest are very permeable to _____ but only slightly permeable to _____. hints the membranes of neurons at rest are very permeable to _____ but only slightly permeable to _____. na+; cl– k+; na+ k+; cl– na+; k+

Answers

The membranes of neurons at rest are very permeable to K+ but only slightly permeable to Na+. The sodium – potassium pump carry both Na and K ion through the membrane to balance the leakage. Na+ is pushed out of the cell and K+ is pulled into the cell.

Neuronal membranes at rest are highly permeable to potassium ions (K+) and slightly permeable to sodium ions (Na+), which contributes to the neuron's resting membrane potential.

The membranes of neurons at rest are very permeable to potassium (K+), but only slightly permeable to sodium (Na+). In its resting state, a neuron's cell membrane has numerous potassium leak channels that allow for the efflux of K+ ions, contributing to the negative resting membrane potential inside the neuron. On the other hand, the permeability of the neuron's membrane to Na+ is significantly lower; there are very few sodium leak channels, and the Na+ ions that do enter are actively pumped out by the sodium-potassium pump.

The wolves and moose of Isle Royale are the focus of the longest-running study of a predator-prey system in the wild. Both are recent arrivals to Isle Royale: moose swam to the island in the early 1900’s. Wolves followed decades later, traveling over the ice from Canada in the 1940’s.About 40 years into the study, the wolf population crashed when humans introduced the canine-parvovirus. Additional factors over the years have impacted both populations. At one point during the study, the moose population collapsed during the most severe winter on record followed by an outbreak of moose ticks. What point on the graph represents the outbreak of moose ticks and a drastic decline in the moose population? A) Point A B) Point B C) Point C D) Point D

Answers

Final answer:

The question asks for a point on a graph which indicates an outbreak of moose ticks and a rapid decline in the moose population in the context of a predator-prey system study. The point of interest should show a notable drop in the moose population, after a decrease due to a harsh winter and before any significant downward trend in the wolf numbers.

Explanation:

Without the accompanying graph, it's difficult to definitively point out which point represents the outbreak of moose ticks and the consequent drastic decline in the moose population. However, given the context, you'd want to look for a point in the graph where there's a significant drop in the moose population. This point should fall after the first major decrease representing the severe winter and before any major decreases in the wolf population, if such data is represented in the graph. An understanding of the predator-prey system and effects of disease outbreaks on such systems can aid interpreting the graph.

Explanation:

Multiple 1 (original bacterium) by 2, 12 times

1*2*2*2*2*2*2*2*2*2*2*2*2 = 4096

4096 bacteria would be present after 4 hours as they grow via binary division.

As it is given that bacteria divides at every 20 minutes mean 2 cells are formed from 1 cell. And after 40 min 8 (2∧n) bacterial cells are present.

After 4 hours i.e., 240 min= 240/20=12.

So 2∧12 = 4096 cells are present.

Answer:

The answer is D. Glycogen

Explanation:

Glycogen is an energy reserve polysaccharide, which is the main source of blood glucose. Its main function is to be an unlimited energy source for the organism. As is known, glucose is necessary to produce energy in the living being and to perform all the processes that occur in an organism. Glycogen is abundantly found in the liver and in smaller amounts in the muscles.

Growth on the macconkey agar and na plates was recorded as good growth poor growth. what did you use to establish what constituted good growth?

Answers

Microbiological experiments are conducted to analyse the growth pattern and capabilities to consume a substrate and undergo multiplcation in number and mass for multiple microbes. Generally, agar or brotg remains the preliminary substrates for analysis of microbial growth. The usual practices include dilution of the stock solution, plating on the plate and observations after a growth period of atleast 24 hours. The number of colonies appearing on the plate are observed and counted manually or automatically. Using appropriate mathematical formula, the actual number of microbial units can be calculated in thw stock solution.

Thus, based upon number of colonies appearing on the plate, the growth can be distinguished as following:

1. No growth: this refers to no appearance of any growth on plate, neither diluted nor stock solution.

2. Poor growth: Qualitatively, poor growth refers to appearance of only 10 or less number of colonies in the stock solution. Such stocks are further concentrated and re-analysed for growth.

3. Good growth: Good microbial growth refers to appearance of 15 or more colonies in the stock solution. Such solutions are considered as moderately concentrated in nature.

Thus, based upon the above mentioned qualitative analyses, the nature of growth can be determined easily.
