How does change in each independent variable affect the dependent variable?
Explanation:
although independent variables can stand alone dependent variables rely on the independent variables therefore when you change the independent variables the dependent variables can no longer depend on the independent variables.
When cells divide during meiosis, homologous chromosomes separate
independently of each other and are randomly distributed to the gametes.
How does this process lead to genetic variability
During meiosis, gametes receive different combinations of genes, and the offspring resulting from fertilization has a unique set of chromosomes. After fecundation, independent assortment generates unique gene combinations in the new generation.
The independent assortment of homologous chromosomes leads to gamete containing different sets of genes.
During metaphase I of the meiotic cell division, homologous chromosomes line up at the equator plate of the cell in a random mode.
The consequence of this independent assortment is that gametes receive different gene combinations, which increase genetic variation in offspring and may eventually confer an evolutionary advantage.
The independent assortment of homologous chromosomes and the process of recombination by which non-sister chromatids interchange genetic material are well known to increase genetic variation in the resulting gametic (meiotic) cells.

If a galaxy is 1 million light years away, the image that we take today is a picture of the galaxy when it was _______ younger.
ANSWERS;
1 million years
1 day
1 year
100 years
Answer: A) 1 million years younger, if it's 1 million light years away, that's means the image taken is l million years before the current amount of years it is away now. think of it as taking a picture of a moving car, if said car is 10 miles away and you take a picture, after the picture is taken it's no longer that far away.

Consider the following scenario: A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations. What is the main selective pressure in this scenario?
leg length
insect population
drought
fish population
fish population
cuz i know :0
The main selective pressure in the given scenario will be on the fish population. Thus, the correct option will be D.
What is Selective pressure?The selective pressure can be defined as an evolutionary force that causes a particular phenotype to be more favorable in certain environmental conditions than other phenotypes. Selective pressures are the considered forces which can drive the evolution through the process of natural selection. Some phenotypes are more favorable than other phenotypes, depending on the external conditions.
Selective pressures can be detrimental or beneficial to certain phenotypes present within a population. The four main types of selection pressures are the biological factors, such as the predation and disease, the availability of resources, the climatic conditions, and the competition between different species.
Therefore, the correct option will be D.

What is one significant drawback to transferring electricity produced by solar energy from states where sunshine is abundant to states where it is not? Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. The transfer could only occur during the day because solar energy cannot be stored. The transfer could only occur during the day because solar energy cannot be stored. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. The cost to transfer electricity produced by solar energy over great distances can be high.
Answer:
The transfer could only occur during the day because solar energy cannot be stored.
Explanation:
The transfer of electricity produced from solar energy only occur during the day because solar energy cannot be stored at huge level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, very big batteries are needed to store it which can't be made due to very high cost so that's why the solar energy can not be stored.

Sophie visited Carlsbad Caverns with her family during her summer vacation, and she was amazed at the cave’s formations. She learned that the cave was formed from minerals.
Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.

why is active transport necessary for the absorption of amino acids in the blood stream
Answer:
Active transport is a mechanism that requires molecules to move against a gradient of concentration. The procedure needs energy.
The glucose molecules in the gut may be higher than in the intestinal cells and blood – e.g. after a sugar meal.
Explanation:
Active transportation is a process necessary for molecules to travel against gradient concentration. It takes energy to do this.
Ions are transferred to the root hair for the use of mineral ions in plants, which have an increased concentration compared to diluted soil solutions. Active transport occurs to enable the plant to take in the soil around the plant the nutrients it requires.
Glucose molecules in animals must be transported into the blood through the gut wall. In the intestine, glucose molecules may be more concentrated than in the intestinal cells and blood - following a sugar meal, for example. It will then spread from high intestinal concentrations to lower blood levels. This requires no energy.
However, glucose levels in the intestines may be lower sometimes. In that instance, active transport is involved in the transportation of glucose. This procedure requires breath-generated energy.
How do both sodium and potassium ions travel
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
Explanation:
Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.
