Which part of the teenage brain is still developing prefrontal cortex temporal lobe occipital lobe limbic system
Answer:
amygdala
Explanation:
Because the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do. The amygdala is associated with emotions, impulses, aggression and instinctive.
The prefrontal cortex is the part of the teenage brain that is still developing. Thus, the correct option is A.
What is the Prefrontal cortex?The prefrontal cortex may be defined as a region of the brain that is located at the front of the frontal lobe. It performs a variety of functions like planning, personality development, etc. in the life of an individual.
The prefrontal cortex is developing till the completion of adulthood or may be up to the age of 30 to 35.
During this time, teenagers are completely dependent on the part of the brain known as the amygdala which plays functions similar to the prefrontal cortex in teens.
Therefore, the prefrontal cortex is the part of the teenage brain that is still developing. Thus, the correct option is A.

In order to replicate behavior, one must retain it in memory. True or false?
Answer:
True
Explanation:
"One must retain behavior in memory in order to duplicate behavior," is a true statement.
What is a long term memory?Memory can be divided into two distinct classes: short-term and long-term.
After the information has been encoded in the appropriate manner, it is stored in the long term memory for use at a later time. As a consequence, the assertion that "in order to repeat behavior, one must retain it in memory" is validated as being correct.

Scientists are studying the evolution of the sloth. They have fossils from 30, 20, 15 and 10 million years ago. Which fossil is most similar the the modern-day sloth? *
Answer:
30 million years ago
Explanation:
Sloths are slow moving animals and are also cute animals. These animals are mostly found in Central America and South America.
From many many million years sloths have lived on this planet. Sloth have evolved from elephant size to moose size in the past few million years. But scientist have known very little about their nature and about their species.
There are about many fossils from 30 million years to 10 million years but recently scientist have discovered that the fossils of sloth from the 30 million years ago are similar to the modern day sloth.

How do the circulatory system and immune system work together to respond to an injury?
Answer:
The number of white blood cells in the blood can increase during an immune response. These cells travel through the circulatory system and the lymphatic system to an injured or infected area of the body. White blood cells leave the blood vessels and travel into the damaged tissue, where the immune response takes place.
Distinguish between voluntary and involuntary actions.
ANSWER:
DEFINITIONS_____________________________________VOLUNTARY MUSCLES:Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.
__________________________________________________INVOLUNTARY MUSCLES:the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.
_____________________________________DIFFERENCES1) VOLUNTARY MUSCLES are under our control but INVOLUNTARY MUSCLES are not under our control
2) VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles
3) VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.
4) VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.
5) VOLUNTARY MSUCLES require more energy. INVOLUNTARY MUSCLES require less energy.

Answer
Heterozygous i think
Explanation:
Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer: 2
Explanation:
Each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
At the end of cytokinesis, there will be 46 daughter chromosomes in each cell.
MITOSIS:Mitosis is the type of cell division that results in two daughter cells that are genetically identical to one another. According to this question, human cells possess 46 chromosomes, which divides during mitosis into daughter chromosomes called chromatids.Therefore, after cytokinesis, 46 daughter chromosomes will be present in each cell in order to maintain the chromosome number of the parent cell.

Which of the following is NOT one of the four systems into which scientists divide earth
A.biosphere
B.hemisphere
C.geosphere
D.hydrosphere
Answer:
Should be D
Explanation:
The one that is not one of the four systems into which scientists divide earth is hemisphere. The correct option is B.
What are the spheres of Earth?
The four main subsystems of the Earth are the land, the water, the living beings, and the air. The term "spheres" refers to these four subsystems.
They are the "geosphere" (land), "hydrosphere" (water), "biosphere" (life) and "atmosphere," specifically (air).
The biosphere, geosphere, hydrosphere, and atmosphere are the spheres. Together, they are in charge of establishing and preserving the Earth's climate, geological processes, and life.
The main significance of the hydrosphere is that it supports a variety of life forms, is crucial to ecosystems, and regulates the atmosphere. All of the water on the Earth's surface is covered by the hydrosphere.
Thus, the correct option is B.

Answer:
the allele combination for a trait
Explanation:
The genotype describes which alleles (versions) of a gene an organism has. Diploid organisms, such as humans, have two copies of each gene. Sometimes these alleles are the same and the individual is h0m0zygous for that gene. If they are different, the individual is heterozygous for that gene.
The physical appearance of a trait is the phenotype.

C. DNA and RNA have a deoxyribose sugar.
O
D. DNA has thymine and RNA has uracil.
Answer:
Dna and RNA have a deoxribose sugar
The statement (D) is correct. DNA has thymine and RNA has uracil.
What is DNA and RNA?DNA and RNA are both types of nucleic acids, large molecules that are made up of monomers called nucleotides. Nucleic acids are used to store genetic information, which the cell uses to make proteins.
Moreover, nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
Hence, DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

Explanation:
Cytoplasm keeps all the cellular organelles suspended. The cytoplasm helps to keep them in place. It is also the site of most metabolic activities in the cell, and it allows materials to pass easily throughout the cell.
The cytoplasm is the liquid that keeps the cell solid. The correct option is C.
What is cytoplasm?
The cytoplasm is a liquid that is filled inside the cell. Between the cell membrane and the nucleus, there is a jelly-like fluid called cytoplasm. It facilitates material exchange and storage among cell organelles.
Cytoplasm helps the cell to stay still and rigid. It places all the cell organelle into a fixed place and the transfer of ions and molecules is also done by the cytoplasm. It is made up of water, salts, and other various material.
They help in the coming in of the materials and going out of the materials. They also protect the cell from shock and other invasive, they make the cell rigid and flexible and also protect recall from each other.
