During one year, seven coyotes in a population die. Eight immigrate into the population, but none emigrate. If the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? Use this formula: population growth = (birth rate + immigration) – (death rate + emigration) 7 11 12 15
Answer:
Death rate= 7 coyotes
Immigration= 8
Emigration= 0
Population growth= 13
Let’s suppose that the birth rate for the given population is x.
Population growth = (birth rate+immigration) - (death rate+emigration)
13=(x+8)-(7+0)
13=x+1
Move the variable to the left side and change its sign.
-x+13=1
Move the constant to the right side and change its sign
-x=1-13
-x=-12
x=12
Answer: x=12

During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations?
Answer:
The first explanation refers to proximate causation, whereas the second refers to ultimate causation.
Explanation:
The first example refers to proximate causation, whereas the second example to ultimate causation.
What is ultimate causation?The ability of one variable to impact another is known as causality, also known as causality. The first variable might create the second or might change the incidence of the second variable.
Correlation, which shows how much two variables tend to rise or fall together, and causation are frequently misconstrued. Correlation does not, however, automatically imply causality. The variations in both variables could be caused by a third component, for instance.
A statistically significant association has been shown between yellow cars and a reduced accident frequency. Just because there are fewer accidents involving yellow cars does not mean that they are any safer. A third element, such as the person's personality type.
Therefore, The first example refers to proximate causation, whereas the second example to ultimate causation.

Figure 11-1
In which part of the cell does this process shown in Figure 11-1 take place?
Answer:
The correct answer is - in the ribosomes.
Explanation:
The translation is the process that takes place in the ribosomes attached to the endoplasmic reticulum where they decode the codons present in the form of the mRNA to the amino acid chain with the help of tRNA.
Ribosomes are called the factory of the protein. It involves triplet code to translate into the amino acid sequences to produce polypeptide chains or protein.
Thus, the correct answer is - in the ribosomes.

A one-hectare forest community is sampled in early August. The sample yields 12 small trees, 4 types of vines, as well as 17 native shrubs that represent 10 species. What can be estimated from the sample for the shrubs in the forest community?
A. the forest’s productivity
B. the species richness
C. the degree of forest disturbance
D. the stability of the ecosystem
E. the uniformity of species distribution in the ecosystem
Answer:
The correct answer is - B. the species richness
Explanation:
Species richness determines the numbers of different species are present in an ecological community. It is a numerical value or count of different species present in a particular community.
The given information or data can only be used to estimate the species richness in the particular forest community as there is data available about the number of species presnt in this community.

The specific heat of three substances in the image are given in the table.
stamped concrete - 0.75
grass-covered soil - 1.01
Water - 4.18
Place the areas in order based on how fast they’ll heat up on a sunny afternoon. Start with the fastest and end with the slowest.
PLEASE ANSWER QUICKLY I WILL GIVE BRAINLIEST!!
Answer:
Correct answer is A-C-B
Explanation:
Just took the test
The concrete has the lowest specific heat, so it requires very little heat to heat up, making it the fastest substance to heat up; the second is grass, and the third is water, which requires a high temperature to heat up, so A-C-B is the correct order.
What is the significance of the specific heat of the substances?Specific heat is explained as the amount of heat that is needed to raise the temperature by 1 degree, and here the water needs the highest temperature to raise the temperature by 1 degree as a result, even if the water gets a little bit more temperature, it will not be too hot right away.
Hence, the concrete has the lowest specific heat, so it requires very little heat to heat up, making it the fastest substance to heat up; the second is grass, and the third is water, which requires a high temperature to heat up, so A-C-B is the correct order.

List the changes that occur in the zygote after fertilization that contribute to human development
Answer:
Hello! Sorry i am late! Here is my best answer below.
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

the growth of plant seedlings is usually
A.phototropic and gravitropic
B.thigmotropic and gravitropic
C.phototropic and influenced by ethylene
D.gravitropic and influenced by ethylene
Answer:
The correct answer is - A. phototropic and gravitropic.
Explanation:
A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.
The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

What is NOT an adaptation that pioneer species need? *
A. ability to do photosynthesis
B. live without soil
C. the ability to grow tall
D. tiny roots to break down rock
Explanation:
Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

The DNA sequence CAT would be transcribed into which mRNA codon?
Answer:
GUA
Explanation:
Hello There!
These are the base pairs for transcription
IMPORTANT
when transcribing; Adenine transcribes to Uracil not Thymine
so it would be
Adenine to Uracil
Thymine to Adenine
Cytosine to Guanine
Guanine to cytosine
so we want to find the mRNA codon of the dna sequence CAT
Cytosine to Guanine (G)
Adenine to Uracil (U)
Thymine to Adenine (A)
your answer is GUA

The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.
What do you mean by Evolution?Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.
