Why do primates have a longer childhood than other mammals?
It's not a multiple choice question
Answer:
The research shows that for the cortex to evolve to be large, primates need a longer pregnancy, whereas a longer childhood is needed for a larger cerebellum to evolve. This means it is critical for infants to have the right environment to develop crucial skills.

What is brain?
The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath. This arrangement is reversed in the spinal cord, where the gray matter is located within and the white matter is on the outside.
Therefore, The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.

"Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates
A. relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation
B. innate variability because plants have evolved molecular differences to an environmental stimuli
C. unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light
D. inclusive fitness because differences in chlorophyll pigments increase the proliferation of beneficial traits in the population

Explanation:
I personally think it is D. Cause the kinetic energy(motion) is happening while the ball is move fast toward the catchers hand. Then when he catches it the ball stops moving and turns into potential energy(movement about to happen) cause the ball is not moving and the catcher has to return the ball back to who ever.

What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning ! will give brainlist
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

If the Pacific plate is moving at a speed of 5 centimeters per year, how many kilometers will the Pacific plate travel in 1 million years?
Answer: 50 kilometers
Explanation:
From the question, we are informed that the Pacific plate is moving at a speed of 5 centimeters per year. The number of kilometers that the Pacific plate will travel in 1 million years would be calculated as:
= 5 × 1,000,000
= 5,000,000 centimeters
Since 100000 centimeters = 1 kilometer, we would convert 5,000,000 centimeters to kilometers. This will be:
= 5,000,000 / 100,000
= 50 kilometers

presence of setae and parapodia
Explanation:
Annelids are groups of organisms under the phylum "Annelida". They are organisms that possess the following characteristics or features: setae, parapodia, coelom, tentacles etc. However, via the possession of not of the setae and parapodia, annelids have been classified into four major classes viz: Polychaeta, Oligochaeta, Hiradinea and Archiannelida, on the basis of their setae and parapodia mainly.
- Polychaeta: possess numerous setae and parapodia
- Oligochaeta: few setae, no parapodia
- Hiradinea: No setae, no parapodia
- Archiannelida: No setae, no parapodia
Hence, the presence of setae and parapodia will enable the scientists classify annelids into their respective classes.

What occurs during the first stage of protein synthesis
1. The dna unzips, and rna bases match up along a strand.
2. Messenger rna moves out of the cell nucleus
3.transfer rna carries a specific amino acid to the ribosome.
4. Messenger rna attaches to a ribosome
Answer:
The correct answer is - 1. The DNA unzips, and RNA bases match up along a strand.
Explanation:
The first stage of protein synthesis is transcription, which is the process that copies DNA sequences in a complementary sequence into the new mRNA molecule. In this stage, DNA molecule unwinds and unzip, and RNA molecule bind at a strand and elongate by adding new complementary bases with the help of RNA polymerase enzyme. Once the elongation of the RNA molecule ends the termination takes place and a new mRNA molecule that stores information to synthesis amino acid chin is produced successfully.
Thus, the correct answer is - 1. The DNA unzips, and RNA bases match up along a strand.
How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates?
Answer:
Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.
Explanation:
A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.
90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates as it helps to balance the amount of carbohydrates and protein needed for the body to perform its activities.
CarbohydratesBoth carbohydrates and proteins have a vital role in good health. Proteins in our body help to maintain healthy skin, bones, hair and muscles. Carbohydrates give energy to our body parts like the brain, kidney and heart to function properly.
If your diet has only 15% of carbohydrates, then the body will take any measure to get the energy it required for the proper functioning of body parts. The body tries to break down the proteins (that you eat)chemically until it act like carbohydrates.

A group of students was trying to determine which type of soil would rose bushes grow the tallest in. They had five rose bushes that they planted in five different types of soil. The five bushes were all the same type and size in the beginning. The size of the pots were the same, they were watered the same amount and kept in the same light and temperature conditions.
a. What was the question and what was their hypothesis?
b. What was the independent variable?
What was the dependent variable? How do you think they measured it?
What conditions (variables) were controlled during the experiment?
Answer:
The question: Which type of soil would roses bushes grow the tallest in?
Hypothesis: One soil type would help the bush grow taller because each soil has different formulas while they were all water the same, got the same amount of sunlight, and kept at the same temperature.
Explanation:
Don't copy this exactly please, put it in different words because I didn't do well putting it together but there you go, lol.
Hope this helps!!!
a. The question the students were trying to answer was "Which type of soil would rose bushes grow the tallest in?" Their hypothesis was that one type of soil would lead to the rose bushes growing taller than the others.
b. The independent variable in this experiment was the type of soil in which the rose bushes were planted. The dependent variable was the height of the rose bushes. They likely measured the height of the bushes at regular intervals (e.g. daily or weekly) using a ruler or tape measure.
The conditions (variables) that were controlled during the experiment were the size of the rose bushes, the size of the pots, the amount of water, the light and temperature conditions.
What is a variable?A variable is a characteristic or property that can take on different values or can be manipulated in an experiment or study. In science, variables are used to help understand the relationship between different factors or phenomena.
They can be classified as independent variables, which are manipulated by the experimenter, and dependent variables, which are observed or measured as a result of the manipulation of the independent variable. In some cases, there are also controlled variables which are kept constant in an experiment

I know one of the answers is that the lower temperature means the reaction will happen slower, but what’s the second answer?
Answer with Explanation:
Hydrogen peroxide is considered "unstable," thus, storing it in the refrigerator provides two advantages:
1. It slows down thermal decomposition.
The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.2. It prevents photolytic decomposition.
Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a cool and dark place, such as the refrigerator.what category of biological molecule is glucose

Why was miasma theory replaced?
O John Snow collected data that showed that germs cause disease.
O John Snow collected data that showed there was another cause to disease.
O New technology showed that miasma cannot exist.
O New technology showed that germs cause disease.
Answer:
Miasma theory was replaced because John Snow collected data that showed that germs cause disease.
Explanation:
The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.
John Snow, an english physician, was one of the main contributors to the microbial theory of disease. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease.
