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? 35 points

Answers

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

Answers

Answer:

The correct answer is-

4. true

5. Natural selection

6. microevolution

Explanation:

Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.

Thus, it is a true statement.

Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time.  natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.

Thus the option Natural selection is correct.

Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.

Thus, the correct answer is - microevolution.

A cell membrane is very specific about what it allows across. How does t help the cell? ​

Answers

Answer:

Explanation:

The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

How many bacteria will there be after four hours from a single bacterium that divides to produce two cells every 15 minutes

Answers

Answer:

65,536 cells

Explanation:

According to the question, a single bacterium will divide into new cells every 15minutes. Since there are four 15 minutes in one hour, which is 60 minutes, a single bacterium will have divided (4×60/15) times =

= 240/15

= 16 times.

Since a single bacterium will divide 16 times in four hours cells, then in four hours, a single bacterium will have divided into 2^16 = 65536 new cells.

Note that, the number of cells a bacterium cell that will divide in two can be expressed as 2^n where n is the number of times

If a bacterium divides into 2 every 15 minutes, there would be 65536 bacteria after four hours.

The bacterium divides into 2 every 15 minutes. Thus, the cell will divide:

60/15 x 4 = 16 times in 4 hours

Thus:

First division = 2 cellsSecond division = 4 cellsThird division = 8 cellsFourth = 16 cellsFifth = 32 cellsSixth = 64Seventh = 128Eighth = 256Ninth = 512Tenth = 1024Eleventh = 2048Twelfth = 4096Thirteenth = 8192Fourteenth = 16384Fifteenth = 32768Sixteenth = 65536

Answers

Opposite ends have opposite charges.
Explanation:

Oxygen is more electronegative than hydrogen so the electrons of the covalent bonds spend more time closer to oxygen than hydrogen. ... They are linked by hydrogen bonds holding the substance together.

Answer:

B. opposite charges

Explanation:

Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.

Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.

All fish nitrogen into the water as ammonia and organic nitrogen. These chemicals are byproducts of their metabolism and respiration.

Answers

Answer:

The correct answer would be - release/excretes.

Explanation:

In ponds, rivers, or similar ecosystem nitrogen cycle is completed with the help of the fishes. In this ecosystem, the nitrogen cycle initiates with the eating plants or fish food by the fishes and performs metabolism and cellular respiration which produces byproduct ammonia and organic nitrogen as animal waste.

This waste is released or excreted by the fish in the water where the beneficial bacterium helps in restoring nitrogen back to the atmosphere by breaking these wastes.

Certain unusual aspects of brain structure were observed in the brain of Albert Einstein. One interpretation is that he was born with certain differences in his cortex from others that encouraged his scientific and intellectual abilities. What do you think of this explanation and what do you think could be an alternative interpretation

Answers

Answer:

It seems a plausible inference. An alternative hypothesis is one in which this anatomical difference is present in low population frequency, thereby further scientific observations are needed to confirm (or reject) this hypothesis

Explanation:

Albert Einstein's brain exhibited an unusual anatomical conformation in the prefrontal cortex. Intriguingly, this brain area is involved in abstract thinking, thereby it has been suggested that the amazing cognitive capacities of Einstein may be due to his prefrontal cortex. A way to test this hypothesis is by an observational study with the aim at determining if this feature is exclusive of Einstein's brain.

The invoice had an April 8 date. Levin received the goods on April 19 and paid the invoice on April 25. the l.c.m of 5ab and 3ab The Kingdoms James Baldwin There was once a king of Prussia whose name was Frederick William. On a fine morning in June he went out alone to walk in the green woods. He was tired of the noise of the city, and he was glad to get away from it. So, as he walked among the trees, he often stopped to listen to the singing birds, or to look at the wild flowers that grew on every side. Now and then he stooped to pluck a violet, or a primrose, or a yellow buttercup. Soon his hands were full of pretty blossoms. After a while he came to a little meadow in the midst of the wood. Some children were playing there. They were running here and there, and gathering the cowslips that were blooming among the grass. It made the king glad to see the happy children, and hear their merry voices. He stood still for some time, and watched them as they played. Then he called them around him, and all sat down together in the pleasant shade. The children did not know who the strange gentleman was; but they liked his kind face and gentle manners. "Now, my little folks," said the king, "I want to ask you some questions, and the child who gives the best answer shall have a prize." Then he held up an orange so that all the children could see. "You know that we all live in the kingdom of Prussia," he said; "but tell me, to what kingdom does this orange belong?" The children were puzzled. They looked at one another, and sat very still for a little while. Then a brave, bright boy spoke up and said,-- "It belongs to the vegetable kingdom, sir." "Why so, my lad?" asked the king. "It is the fruit of a plant, and all plants belong to that kingdom," said the boy. The king was pleased. "You are quite right," he said; "and you shall have the orange for your prize." He tossed it gayly to the boy. "Catch it if you can!" he said. Then he took a yellow gold piece from his pocket, and held it up so that it glittered in the sunlight. "Now to what kingdom does this belong?" he asked. Another bright boy answered quickly, "To the mineral kingdom, sir! All metals belong to that kingdom." "That is a good answer," said the king. "The gold piece is your prize." The children were delighted. With eager faces they waited to hear what the stranger would say next. "I will ask you only one more question," said the king, "and it is an easy one." Then he stood up, and said, "Tell me, my little folks, to what kingdom do I belong?" The bright boys were puzzled now. Some thought of saying, "To the kingdom of Prussia." Some wanted to say, "To the animal kingdom." But they were a little afraid, and all kept still. At last a tiny blue-eyed child looked up into the king's smiling face, and said in her simple way,-- "I think to the kingdom of heaven." King Frederick William stooped down and lifted the little maiden in his arms. Tears were in his eyes as he kissed her, and said, "So be it, my child! So be it." The little girl who gives the final answer causes the king to feel A) struck by her charm. B) moved by her innocence. C) alarmed by her insight. D) mystified by her identity. 100000000000 to the 10th power what is 660 increased by 1 followed by a further one How fast must the space shuttle go to cover 20,000 meters in 4.0 seconds? ___ use a period within parentheses that is inside a sentence. often sometimesneveralwaysrarely -16 = -5x + x please help Solve 3(x - 1) + 2 = 5x + 6, Answer is a decimal round to the hundredth (2 digits) or use / for fraction bar.
