Explanation:
Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.

. If a suggested daily protein consumption of .8 grams / Kg. Body weight is recommended, how many protein Kcals would be represented in the diet of a 220 lb. Individual with no suggested health concerns or limitations? (Kgs. = lbs. / 2.2 ; The caloric density of protein is 4 Kcals / gm.)
Answer:
The correct answer would be - 320 kcal.
Explanation:
Given:
Required protein amount is - .8 grams/kg
kg = lbs/2.2
weight = 220
then, weight in kg = 220/2.2 = 100 kg
solution :
requied amount of protein in normal individual:
= 100* 0.8
= 80 grams.
Now kcal by this amount of protein would be :
= 80*4
= 320 Kcal
Thus, the correct answer would be - 320 kcal.
The amount of protein Kcals in the individual's diet would be 320 Kcals.
The recommended daily protein consumption = 0.8grams / Kg body weight
The body weight of the individual is given as 220 lbs.
The weight of the individual would need to be converted to Kg.
Conversion factor between Kg and lbs is given as: 1 Kg = 2.2 lbs
The weight of the individual in Kg = 220 lbs * 1 kg /2.2 lbs ) = 100 kg
Amount of recommended protein intake of the individual based on body weight will be: 0.8 grams/ Kg * 100 Kg = 80 grams
Caloric density of protein per gram = 4 Kcals / gram
Therefore, protein Kcals in the individual's diet will be 4 Kcals / gram * 80 grams = 320 Kcals
The amount of protein Kcals in the individual's diet would be 320 Kcals.

Using information from the diagram, state one reason why the movement in the third image represents active transport
Answer:
A protein or ion has passed through the "pump" or carrier proteins and move within the cell.
Nvm short and sweet ;)
Further info..
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

Cells can best be described as
Cells can best be described as the fundamental units of life. They are the building blocks of all living organisms, including plants, animals, and even microorganisms.
Here are some key characteristics that describe cells:
1. Structure: Cells have a defined structure with a plasma membrane that separates the internal components of the cell from the external environment. Inside the cell, there is a variety of organelles, such as the nucleus, mitochondria, and ribosomes, each playing a specific role in cell function.
2. Function: Cells carry out various functions necessary for life. They perform metabolic processes, such as respiration, photosynthesis, and protein synthesis. Cells also maintain homeostasis, which involves regulating internal conditions to keep the cell functioning optimally.
3. Reproduction: Cells have the ability to reproduce. They can divide and create new cells through processes like mitosis and meiosis. This ensures the growth, development, and repair of tissues and organs.
4. Genetic Material: Cells contain genetic material in the form of DNA (deoxyribonucleic acid). DNA carries the instructions for cellular activities and determines the characteristics of an organism. It is organized into genes, which are passed on from one generation to the next.
5. Specialization: Cells can be specialized to perform specific functions within an organism. For example, muscle cells contract to enable movement, while nerve cells transmit electrical signals for communication. This specialization allows multicellular organisms to have different cell types that work together to maintain overall function.
Overall, cells are the basic structural and functional units of life. They are responsible for all the processes necessary for an organism's survival and are crucial for maintaining life's complexity and diversity.

Which statement best accounts for the decline in bighorn sheep populations? 1. Predators of the sheep decreased in number. 2. Sheep ewes that have shorter, spiked horns increased in number. 3. Human activities directly and indirectly affected the sheep. 4. The sheep were listed as a "species of concern" by Glacier National Park.
Answer:
The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."
Explanation: Explaination of the following statements -
Predators of the sheep decreased in number.Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.
Thus , this statement is not correct.
Sheep ewes that have shorter, spiked horns increased in number -The larger, wild relative of the domesticated sheep is the bighorn sheep. Males are called "rams" and have long spiral horns, while females are called "ewes" with shorter, spike-like horns. With white areas on the muzzle, the back of the legs and around the rump, the coat is short, coarse and usually brown. The sheep will shed its hair once a year to reveal a new coat underneath.Thus , the statement does not match with the decline of the bighorn sheep.
Human activities directly and indirectly affected the sheep. -: Disease transmission, human interference, overgrazing, and loss of habitat are often cited as factors responsible for decreases in the abundance and distribution of bighorn sheep. these all factors comes under the human activities which directly /indirectly results in the declination of the bighorn sheep.Hence, this statement is correct .
The sheep were listed as a "species of concern" by Glacier National Park.Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered. The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is. Therefore , the national park indicated the species at risk , but were not responsible for their declination.
Hence, this statement is incorrect.
Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)

Suggest a hypothesis to explain why the radiation occurred.
Answer:
An example of an adaptive radiation with evidence to support the claim that the radiation originated with one or a few species is discussed below in details.
Explanation:
The method of evolution of various classes in a given geographical area originating from a spot and spreading to other regions or habitat is described as adaptive radiation. For example, modifications in nozzles of finches on Galapagos island.
Adaptive radiation indicates the adaptation of an organism that allows it to favorably spread, or radiate, into other circumstances. Adaptive radiation commences to speciation and is only used to explain living organisms.
A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc). Half of the offspring from the cross had curly wings, and the other half had straight wings. Identify the genotype and phenotype of the second parent fly. State the evidence that supports your response.
Answer:
The other fly would have to be a cc
Explanation:
To do this, you can use the square method, one Cc's on the top and one side a cc, when you cross these it gives you Cc, Cc, and cc, cc. Half and half.
Hope this helped!
The other parent was cc.
Genes often occur in pairs. Genes are units of inheritance located in the chromosomes. The pairs in which genes occur are called alleles. In a given pair of alleles, one gene is dominant and the other is recessive.
In this case, the dominant gene is for curly wings and the recessive gene is for straight wings. If one parent is Cc , the other parent must be cc causing half of the offspring from the cross to have curly wings, and the other half to have straight wings.

145,000 mg
1,450 mg
1.45 mg
O
145 mg
Grams can be converted into milligrams by multiplying the amount in grams by 1000. Therefore, 1455 grams will be equivalent to 1,455,000 mg. Thus, the correct option is A.
The conversion of metric units from one unit to another can be done by multiplication or division by powers of 10. If the unit is to be converted into a bigger unit, it has to be divided, whereas if the unit is to be converted into a smaller unit, it has to be multiplied.
Thus, the conversion of gram to milligram is conversion of a unit into a smaller unit and the amount, therefore, has to be multiplied.
There are 1000 milligrams in 1 gram. Therefore, 1,455 grams will have 1000 × 1,455 = 1,455,000 milligrams.
