Answer:

Not all DNA that was found at the scene has to be related to the scene.

Explanation:

Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.

Answer:

Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

Answer:

B.) in all directions

Explanation:

Ball-and-socket joints are as the name implies. A ball-shaped end of bone attaches to an indentation on another, the socket. It rotates around in any direction, with an example being the end of your arm that attaches to your torso. This design makes it more mobile than any other type of joint.

Answer:

Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.

Explanation:

The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.

The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.

Explanation:

Electromagnetic radiation transmitted by the sun. Sunlight based radiation can be caught and transformed into helpful types of energy, for example, warmth and power, utilizing an assortment of innovations. Notwithstanding, the specialized plausibility and practical activity of these advancements at a particular area relies upon the accessible sun oriented asset.

Each area on Earth gets daylight in any event part of the year.

The measure of sun based radiation that arrives at any one spot on the World's surface differs as indicated by:

Geographic area

Time of the day

Season

Local landscape

Local weather

The turn of the Earth is likewise liable for hourly varieties in daylight. In the early morning and late evening, the sun is low in the sky. Its beams travel further through the environment than around early afternoon, when the sun is at its most noteworthy point. On a sunny morning, the best measure of sun based energy arrives at a sunlight based gatherer around sun oriented early afternoon.

Man does not have a haploid life cycle. Haploid life cycle is observed in most of the single-celled organisms. Thus, the given statement is false.

The haploid life cycle is the simplest type of life cycle. It is found in most of the single-celled eukaryotic organisms. Organisms with a haploid life cycle spend the majority of their lives in haploid forms as haploid gametes. When these haploid gametes fuse, they form a diploid zygote.

The life cycle of Man is an example of diploid life cycle. The human life cycle involves a mature human cell (2n), eggs are produced by meiosis in the ovary of a woman, and sperms are produced by meiosis in the testis of a man. The eggs and sperm combine in fertilization to form a diploid zygote (2n).

Answer:

50%

Explanation:

Based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.

A pie chart can show the method by which a total amount can be divided between the levels of a categorical variable as a circle is divided into radial slices.

Each categorical value is corresponding to a single slice of the circle, and the size of each slice, both in the area and arc length, is indicative of the proportion of the whole that each category level will take.

Pie charts have comparatively limited cases of use this is encapsulated particularly accurately according to its definition.

So, for the utilization of a pie chart, one must have some kind of a whole amount that is divided into a number of distinct parts. These are represented by various sections.

Therefore, based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.

There are two parts in the plants  ----

1. the shoot system

2. the root system

Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.

The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.
