Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

13. Which statement correctly compares a function of lipids to a function of proteins in the body?
A. Fats insulate the body, and proteins control contraction.
B. Fats cushion the organs, and proteins insulate the body.
C. Fats coordinate body activities, and proteins provide sugars.
D. Fats store energy, and proteins provide the primary fuel for cell respiration.
The correct answer is A.
Fats thermally insulate the body, while proteins like actin and myosin form myofibrils which are the anatomical support for contraction.
Lipids and proteins are the macromolecules present inside living cells. Lipids are made of fats that insulate and proteins are involved in contraction. Thus, option A is correct.
What are the functions of lipids and proteins?Lipids have been the polymers that make the larger molecules and have been constituted of glycerol and fatty acids (triglycerides). These are stored in the fatty tissues called adipose tissues and provide insulation to the body.
On the other hand, proteins are macromolecules constituted of amino acid sequences (polypeptide). These are involved in the muscle contraction that allows the movement and motion of the muscular and skeletal systems.
Therefore, option A. the fats and proteins are involved in insulation and contraction.

Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar levels normal, but hormones produced during pregnancy deactivate the cells. After pregnancy, hormone levels return to normal, and so do the pancreas cells. Is this an example of DNA or the environment controlling gene expression? Explain your answer
Answer:
environment controlling gene expression
Explanation:
Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.
The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.
Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.
This it is a result of the environment control gene expression.

We have heard that we are a product of our DNA. Specific genes in the
chromosomes we inherit from our parents help determine the traits we
inherit. Using the illustration identify the letters that represent the
three structures mentioned: DNA, chromosome, and gene
Answer:
A.) A.DNA; D.Chromosome; E.Gene
Explanation:
The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria. Everything a person needs to grow and operate is encoded in their genome.
What is the genome organization in cell?The single linear bits of DNA that make up genomic DNA are connected to a protein called a nucleoprotein complex.
Chromosomes are made of a DNA-protein complex, and the 23 chromosomes found in the cellular nucleus are where almost all the genomic DNA is dispersed.
A genomic organization is the division of DNA molecules into chromosomes and their linear arrangement.
In addition to the three-dimensional structure of chromosomes, “genome organization” can also refer to the arrangement of DNA sequences inside the nucleus.
Therefore, A.DNA; D. Chromosome; E. Gene

What keeps cells from growing indefinitely?
Answer:
Apoptosis
Explanation:
Apoptosis is a process that some cells go through when their embryo divides. It is programmed cell death. Apoptosis can help protect organisms from developing cancerous growths, or the uncontrolled growth/division of cells.
Well Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, because the inside grows a faster rate than the outside.

write a five sentence paragrgh explaining the cell cycle
Answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.
New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.
The two main parts of the cell cycle are mitosis and interphase.
Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”
The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.
Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.
Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.
