Answer:
The correct answer is - The point closest to the scalp.
Explanation:
In order to analyze a strand of hair investigators need to collect the DNA. To analyze a strand of hair the DNA must be nuclear DNA which can be found at the root of the hair near the scalp as the point, hair attached to the scalp there are cells that can provide the nuclear DNA. Any other section or the part of the hair strand does not contain the nuclear DNA so analyze DNA would not be possible.
mutations are caused by the way genes from both parents combine, and they do get passed on. True or False
Answer:
That's True
Explanation: Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. :)

3. Which of the following is a defining characteristic of a prokaryotic cell?
a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement
Answer:
C
Explanation:
Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.
The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.
What is a prokaryotic cell?Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.
They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.
The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.
Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.
Answer:
C.
Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Hope this helps! Have a nice day!
Answer:
C. to produce a new cell
Explanation:
Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.
an element has 6 protons and 6 nuetrons what is its atomic number and its mass number.
Answer:The number of protons is equal to the atomic number of the element. For this element having 6 protons makes the atomic number 6 and makes the element Carbon. For this element 6 protons and 6 neutrons combine to make an atomic mass of 12 amus.
Explanation:
Answer:
the atomic number is 6 but the mass is 12
Explanation:
Why is it important for gametes to be haploid cells?
The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.
Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.
Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.
Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.
Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

population sizes of three African animals in 1990 and in 2000.
Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

A. tasting a pasta sauce after adding a new ingredient B. looking at a blood sample through a microscope C. a dog buries a bone in the backyard D.listening to bats of different materials hitting a baseball
Answer:
C. a dog buries a bone in the backyard
Explanation:
A dog burying a bone in the backyard is not an observation in terms of scientific methods.
Observation is the process of acquiring data about a phenomenon under study.
Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.
Also, we can use some specialized equipment to make observations.
A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.
