A population of birds exhibits Type II survivorship. A predator is introduced that feeds on hatchlings, causing a change in the survivorship of the birds. Which of the following would most likely represent survivorship of the birds after the introduction of the predator? the answer choices are the images below.
Answer:
D
Explanation:
I took the test and got it correct
The fourth graph would most likely represent survivorship of the birds after the introduction of the predator. Thus, option D is correct.
What the population of birds exhibits Type II?A population of birds exhibits Type II survivorship. A predator is introduced that feeds on hatchlings, causing a change in the survivorship of the birds. A survivorship curve refers to a graph showing the number or proportion of individuals surviving to each age for a given species or group. There are three types of survivorship curves as follow:
Type I curves depict individuals that have a high probability of surviving to adulthood. For example, large mammals have type 1 survivorship curves, because they have a. low infant mortality and high rates of survival into old age.
Type II curves also called as intermediate type, it depict individuals whose chance of survival is independent of age. For example, most birds have type 2 survivorship curves birds die more or less equally at each interval of their age.
Therefore, The fourth graph would most likely represent survivorship of the birds after the introduction of the predator. Thus, option D is correct.

Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!
Hope this helped!

List 5 uses for proteins in the cell.
Answer:
Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Finally, they keep your immune system strong, transport and store nutrients and can act as an energy source, if needed.
Explanation:
Hope this helped Mark BRAINLIEST!!!
Proteins help in cell structure formation, and cell transport, allow biochemical reactions, cell repair and also help in cell division.
What are cellular proteins?Proteins present in the cell are of various kinds. They are formed in the cell by the process of DNA transcription and translation.
The proteins formed in the cell then go on to perform various functions. The cellular proteins form the structure of the cell. They do that either by forming the cell membrane or the membrane of the organelles.
The cellular proteins also help in transport of nutrients. This transport is of two types. It can transport materials from inside to outside of the cell and vice versa. It can also transport materials inside the cell to other organelles.
Various biochemical reactions in the cell are possible because of the cellular proteins. The proteins formed in the cell are also used for cell repair and cell division.
Therefore, the various functions performed by the cellular proteins are cell structure formation, cell transport, allowing biochemical reactions, cell repair and help in cell division.

Answer:
gas moves more freely because it has loosely arranged molecules
Explanation:
how are adaptation and variation similar?
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

B chromosomes
3.2.2 Chromosome
A chromatid
B spindle fibre
3.2.3 Phases in the cell cycle
A interphase

3.2.5. None
Explanation:
- 3.2.1
Mitosis is a kind of cellular division that produces two genetically identical daughter cells. Whereas, cloning is a technique used to create identical cells. This means that mitosis applies to cloning.
- 3.2.2
A chromatid is a half of a replicated chromosome. Together, a replicated chromosome is called SISTER CHROMATIDS. One of them is called a Chromatid. Spindle fibre is a structure involved with the division of the genetic material during cell division.
- 3.2.3
The cell cycle consists of two stages interphase and mitotic phase. Hence, interphase and mitosis are part of the cell cycle.
- 3.2.4
A tumour is a cancerous mass of cells. Tumour can either be BENIGN i.e. not capable of spreading to other parts or MALIGNANT i.e. capable of spreading to other parts.

To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.
A) Gene Flow
B) Random Mating
C) Selection
D) Mutations
Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.In consequence, random mating acts to prevent any change in the allele frequencies.In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

2. In July, a student tested the soil in two plots and calculated the
concentration of nitrogen compounds present in each plot. The student
then planted 20 seedlings in the first plot and allowed them to grow.
Nothing was planted in the second plot. The student tested the soil in both
plots again after one month. The concentration of nitrogen compounds
had decreased in the first plot but had remained the same in the second
plot. Which of the following best explains the decrease in nitrogen
compounds in the first plot? *
A. The nitrogen compounds had broken down into elements.
B. The nitrogen compounds were absorbed by the seedlings for their growth.
C. The nitrogen compounds escaped through air pockets created by the seedlings'
roots.
D. The nitrogen compounds had evaporated because of the warm summer
temperatures.
Answer: B. The nitrogen compounds were absorbed by seedlings for their growth.
Explanation:
For the plant to have energy accessible when and where it needs it to maximize yield, nitrogen is essential. As proteins and enzymes control water and nutrient intake, this important nutrient is even present in the roots. Thus, option B is correct.
What nitrogen compounds were absorbed by the seedlings?Plants absorb ammonium and nitrate during the assimilation process, and these substances are then converted into organic molecules containing nitrogen, such as DNA and amino acids.
Plants may absorb substances from soils like nitrate, nitrite, ammonia, and ammonium, which are subsequently utilized to create proteins in both plants and animals.
Therefore, The nitrogen compounds were absorbed by the seedlings for their growth. After they reach three inches in height, seedlings should be fertilized; after that, they can get weekly fertilization until being transplanted.
