What factors contributed to the shift from hunting and gathering to agriculture?
This is a biotechnology question but there isn't a subject choice for it.
Answer:
One of the main factors was a lack of wild animals suitable for hunting and a lack of plants suitable for gathering.
Explanation:
This in turn was due to either climate change or to animal population declines because of unsustainable volumes of hunting and gathering

Which factor contributes to the formation of tides that turn turbines to create energy in the ocean?
wind speed
water density
Earth’s rotation
water temperature
The factor that contributes to the formation of tides that turn turbines to create energy in the ocean is Earth's rotation.
What is Tidal energy?Tidal energy is a type of renewable energy that is generated by the movement of water due to the gravitational forces of the moon and the sun.
As the Earth rotates, the gravitational forces of the moon and the sun cause the water in the ocean to move, creating tides that rise and fall twice a day.
This movement of water can be harnessed by turbines, which are placed in areas of high tidal flow. As the tides move in and out, the turbines spin, generating electricity that can be used to power homes and businesses.
While factors such as wind speed, water density, and water temperature can all affect the movement of water in the ocean, they are not the primary factors that contribute to the formation of tides.
The tides are primarily driven by the gravitational forces of the moon and the sun, which cause the water to move in a predictable pattern that can be harnessed for energy generation.

Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

briefly explain natural selection
Answer:
Explanation:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
“How is it possible that siblings with the same parents can have such different traits, such as skin tone?”

Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses. The molar teeth developed and became stronger. Which statements are supported by this evidence?
A) Molars became bigger to fit into the jaw structure of modern horses.
B) The molars of the horses underwent changes so they could chew meat.
C) The digits were modified to enable the horses to graze better on hard, rocky surfaces.
D) The emergence of grasslands over time led to the development of strong molar teeth in horses.
E) The digits of the horses’ feet underwent modifications, enabling them to run faster from predators.

the wing of a penguin is ________ the arm of a human.
The wing of a penguin is homologous to the arm of a human.
Homologous organs refer to organs of different organisms that are structurally similar but functionally different.
The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.
Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.

The brain of mammals keeps track of the temperature of the skin and the blood so that they can regulate the cells and maintain homeostasis in the body relative to the outer environment.
What is the importance of homeostasis in the body?The body's homeostasis should always be maintained in order to keep the cells and organs active and able to perform their functions. Because the brain has different control centers, it keeps track of the skin and blood temperature because the brain can release different hormones depending on the situation. The lipid composition and arrangements of the cells change in the summer and the winter, and all these are possible due to the brain sending signals to cells.
Hence, the brain of mammals keeps track of the temperature of the skin and the blood so that it can regulate the cells and maintain homeostasis in the body relative to the outer environment.
