Please answer number 4! It’s a do-now!

Answer:

A

Explanation:

It provides energy to move molecules against the concentration gradient.

The role of ATP in the process of active transport is it provides the energy that cells need to move molecules against a concentration gradient. The correct option is A.

Active transport occurs when a molecule moves against the concentration gradient from an area of lower concentration to a region of greater concentration. Because active transport involves moving biochemicals from low-concentration locations to high-concentration areas, it requires chemical energy.

The movement of macromolecules like proteins and lipids into and out of the cell depends heavily on ATP. The energy needed for active transport mechanisms to move such molecules over a concentration gradient is provided by the hydrolysis of ATP.

Therefore, the correct option is A. It provides the energy that cells need to move molecules against a concentration gradient.

- Not enough evidence

 Sometimes there isn't enough evidence in a case to state fully what happened which can result into false accusation. It can also make the jury become confused and struggle to find whos the right murder due to the lack of evidence.  

- misinterpreted evidence

If a forensic scientist looks at a piece of evidence with the wrong theory they might try to prove their theory by trying to get proof out of it which can cuse a domino effect to where the wrong person can be accused of the wrong thing.

- false evidence

The evidence may be planted and the forensic science can look at it the wrong way similar to misinterpreted evidence. usually forensic scientist can see that it has been planted but when they figure that it has then its even harder to look for the real evidence. and it would take a longer process. And if they present the false evidence in court it may take a bad turn.

Answer:

Explanation:

Proteins are macromolecules that are important in the development and repair of bones and tissues. Since good sources of proteins are made up of essential amino acids, they contribute greatly to the well being of children based on the roles of these essential amino acids.

When children do not have this protein there diet, they could have stunted growth and weak bones (due to absence of protein for bone and tissue development), fatigue (absence of protein for development of muscle thus not enough glycogen is stored in the muscle cells),  slowed/stunted growth (absence of proteins for the development of bones and tissues) and this children also have reduced immunity because of the absence of proteins which releases amino acid for immune/antibody formation.

Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like an asteroid striking Earth or a large volcano erupting in the past have all contributed to mass extinctions.

Extinction is defined as the loss of a species or a group of species as a result of environmental factors or evolutionary changes in individual species.  There is a continual loss of species from Earth, and the rates have changed over time. IUCN Red List predicts that 25% of mammals are in danger of going extinct. Extinction is, in a sense, natural.

Populations divide into new species as a result of speciation, which boosts biodiversity. There are times of adaptive radiation following extinctions, during which time new species fill empty niches. Geographic isolation caused by shifting tectonic plates allows populations to divide into new species. The Permian-Triassic extinction, sometimes known as the "Great Dying," occurred around 252 million years ago.

Thus, extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like an asteroid striking Earth or a large volcano erupting in the past have all contributed to mass extinctions.

The giant impact theory — the idea that a catastrophic collision about 4.5 billion years ago between Earth and a protoplanet about half Earth's size created a disk of molten rock, gas and debris that consolidated to form the moon — was first set forth in the mid-1970s.

The most normally invoked grounds for lunar formation maintain that a giant protoplanet is sometimes called Theia.

When the Chemical differentiation and crystallization delivered dense material that sank to the bottom of the lunar magma ocean and a spirited crust that created the lunar highlands.

The numerous commonly invoked justification for lunar formation holds that a giant protoplanet, sometimes called Theia, struck the recently formed Earth 4.5 billion years heretofore and formed a cloud of debris that fast coalesced into the moon.

But that hypothesis has mourned from a nagging flaw. Simulations of moon-forming crashes have shown Theia would have stood as the immediate donor of lunar material.

But commentaries of Apollo moon rocks have authenticated that the moon appears in many ways a chemical clone of Earth, not Theia.

Explanation:

Yellowstone Hot Spot-North American Plate is correctly matched to its overlying tectonic plate.

Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.

There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.

The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

• Selective permeability is a characteristic and function of the cell membrane, which plays an important role in sustaining homeostasis by monitoring the passage of certain substances while inhibiting others from invading the cell.  

• Of the given options, a window screen is an example of selective permeability.  

• A window screen is also known as the bug screen, insect screen, wire mesh, or fly screen is created to cover the window opening.  

• It is generally a mesh formed of fiberglass, metal, pieces of plastics, plastic wire, and pieces of metal or wood.  

• It functions to prevent the entry of bugs, birds, debris, and other animals into the building, however, it does not prevent the entry of fresh air.

According to H-W, a population is in equilibrium if it meets five conditions, and have the same allelic and genotypic frequencies through many generations. 1) Infinite population size / 2) p=0.9 and q=0.1 / 3) 25 cats

-------------------------------------------------------

Let us review some theoretical framework about Hardy-Weinberg equilibrium, while we answer the questions.

⇒ Hardy-Weinberg assumption for a population in equilibrium:

Q1. Identify ONE of the five conditions required for Hardy-Weinberg equilibrium that this population of cats does not meet.

Since this population is composed of two Siamese and three Persian cats, the condition that this population does not meet is infinite population size.

This population is under the effect of genetic drift for being only 5 individuals colonizing an island.                                    

                                           *****************

⇒ According to Hardy-Weinberg, p and q represent the allelic frequencies in a locus, referring to the allelic dominant or recessive forms.  

The genotypic frequencies after one generation are p² (H0m0zyg0us dominant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive).  

Populations in H-W equilibrium will get the same allelic frequencies generation after generation.

Being

Q2. If you assume Hardy-Weinberg equilibrium for this population, what would be the frequencies of the two alleles after 10 generations?

Allelic frequencies, f(x), are

If this population is in H-W equilibrium, the allelic frequency will be the same through many generations.

So, after 10 generations, the allelic frequencies will still be p = 0.9 and q = 0.1.

Q3. Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?

We know that,

To get the number of individuals with folded phenotype, we should get the phenotypic frequency, which equals the genotypic frequency because it is the recessive phenotype.

Genotypic and Phenotypic Frequency

Now that we have the phenotypic frequency, we just need to multiply it by the total number of individuals in the population, N.

N = 2500 individuals

So, after 10 generations and a population size of 2500 cats, there will be 25 folded-eared individuals.
