What evidence have you discovered to explain what structure surround a cell, such as an ostrich egg, and how these structures help a cell function
Answer:
plasma membrane
Explanation:
An ostrich egg is the largest egg of any living bird. The eggshell of an ostrich egg is shinny, glossy and is cream in color. It is more oval than the egg of a chicken.
The structure of a cell comprises of the components with their specific functions which is essential to carry out the various processes of life. In an eukaryotic cell, the outer lining is known as the plasma membrane. It helps to protects the cell and separates it from the surroundings environment.
The plasma membrane is made up of proteins as well as lipids and other fat like molecules.

What is the strongest acid listed in 2-2?
What is the weakest acid listed in 2-2?
What is the strongest base listed in 2-2?
Answer:
Strongest acid is hydrochloric acid
Weakest acid is rainwater
Strongest base is sodium hydroxide
Explanation:
pH is defined as the measure of hydrogen ion concentration in a particular solution. pH values seen between 0 and 1 are actually known to be strongest acids. Weakest acids are the ones that move towards neutrality. The neutral pH value is 7.0.
Looking at their pH values, we will discover that hydrochloric acid is the strongest acid. Rainwater is weakest acid because it moves towards neutrality. Sodium hydroxide is the strongest base.
In pH, values between 0-6 are referred to being acidic, 7 is neutral and while 8-14 are basic.

B. Gene, DNA, Chromosome, Nucleus and Cell
C. Cell, Nucleus, Chromosome, DNA and Gene
D. None of the above
Answer:
I hope this helps just to let you know this is what I searched just being honest :)
Explanation:
DNA
But your genes also mean that you probably look a bit like other members of your family. For example, have you been told that you have 'your mother's eyes' or 'your grandmother's nose'?
Genes influence what we look like on the outside and how we work on the inside. They contain the information our bodies need to make chemicals called proteins. Proteins form the structure of our bodies, as well playing an important role in the processes that keep us alive.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.
27 DNA.gif
The DNA double helix showing base pairs
The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.
There are four types of base: adenine (A), thymine (T), guanine (G) and cytosine (C). These bases link in a very specific way: A always pairs with T, and C always pairs with G.
The DNA molecule has two important properties.
It can make copies of itself. If you pull the two strands apart, each can be used to make the other one (and a new DNA molecule).
It can carry information. The order of the bases along a strand is a code - a code for making proteins.
Genes
A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood.
Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes. These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.
Chromosomes
If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand 6000 million miles long (but very, very thin)! To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes.
105-Gene-unwrapped.gif
The packaging of DNA into chromosomes
Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.
The sex chromosomes determine whether you are a boy (XY) or a girl (XX). The other chromosomes are called autosomes.
106-autosomes.gif
The karyotype of a male human being
The largest chromosome, chromosome 1, contains about 8000 genes. The smallest chromosome, chromosome 21, contains about 300 genes. (Chromosome 22 should be the smallest, but the scientists made a mistake when they first numbered them!).
The DNA that contains your genes is stored in your cells in a structure called the nucleus.
Which of the following is an irrational number?
how can genetically modified bacteria with human genes be used to treat human diseases
In the 1980s, scientists discovered how to produce human insulin by transplanting the genetic information for the human insulin hormone from a human cell, into the DNA of the E. coli bacterium. This reprograms the bacteria to produce insulin, in just the same way as they make their own proteins.
the cells produced during meiosis are?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

to assist other lymphocytesto kill cells infected with a virus or cancerto help in the body's immune responseWhat are T-lymphocytes?
T-lymphocytes, also known as T cells, are a type of white blood cell that plays a key role in the immune system. They are produced in the bone marrow and mature in the thymus gland.
One of the main functions of T-lymphocytes is to assist other lymphocytes, such as B cells, in the immune response. They do this by releasing chemicals that help to activate and coordinate the immune response, and by directly attacking infected cells.
T-lymphocytes also have the ability to kill cells that are infected with a virus or cancerous cells. They do this through a process called cell-mediated immunity, in which they recognize and bind to specific proteins on the surface of infected cells. Once they have bound to the infected cells, they release chemicals that kill the cells, helping to prevent the spread of the infection or cancer.
T-lymphocytes are an important part of the body's immune system and play a vital role in helping to protect the body against infections and disease.

A population of rabbits in an ecosystem has genetic variation in fur thickness. Some rabbits have thick fur and others have thin fur. Due to changes in the environment, the average temperature of the ecosystem is steadily increasing.
How will this environmental change likely affect the rabbit population over time?
A. Rabbits with thick fur will become more common in the population because thick fur will be a favorable trait in this changing environment.
B. Rabbits with thin fur will become more common in the population because these rabbits are more likely to survive and successfully reproduce.
C. Rabbits with thick fur and thin fur will become equally distributed because all rabbits in the population will successfully reproduce.
D. Rabbits with both fur types will increase in the population because the temperature change will cause the population of rabbits to expand.
Answer:
B
Explanation:
Thin fur is better for warmer weather, so the rabbits with thinner fur won't over heat in the warming weather.
The population of rabbits n the genetic ecosystem has thick fur and others have thin fur, due to the changes in the climate avg temperature of the ecosystem is steadily falling.
Looking at the situation and adaptive powers or abilities of the animals the thick fur will survive longer than those of the thin fur as the temperature of the place is declining.Hence the option A is correct.

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or populations? explain
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.
