Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?

Answers

Answer:

the signals have different frequency

Explanation:

The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.

D.anywhere its service broadcasts and it can receive a signal.

Explanation:

The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavyweight. This flow is due to great temperature differences from the bottom to the top of the mantle. The movement of the mantle is the reason that the plates of the Earth move! The temperature of the mantle varies from 1600 degrees Fahrenheit at the top to about 4000 degrees Fahrenheit near the bottom!

Answers

Answer:

Silent mutations do not affect protein function

Explanation:

A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.

Despite the best efforts of scientists to create an all-encompassing system of names for relationships between organisms, some still fall in a grey area. Some species of wasp are known as "parasitoids" and not true parasites. These wasps kill caterpillars to reproduce but do not harm any other caterpillars until they need to reproduce again. Why aren't these wasps considered true parasites?

Answers

Answer:

Wasps only use the caterpillars when producing offspring which kills the caterpillars.

Explanation:

'True parasites' are generally defined as organisms which live off 'host' organisms of another species at the expense of that organism by harming them in some way. They do this in a variety of ways for different reasons, the most common ones being as a source of food or favorable living conditions. Their lives are almost always entirely dependent on their host. Conventional parasites also usually don't kill their hosts as it is in their best interest that their host stays alive for them to gain the most advantage from them.

Wasps do not fit the true definition of a parasite because:

1. They don't rely on living off the caterpillars to live normally. Wasps are able to find their own sources of food and live on their own without other species. It is only when reproducing that they use and harm the caterpillars.

2. This process kills the caterpillars as the wasp larvae eat them when they emerge and grow which is unconventional for parasites.

It is because of these exceptions that these wasps are classified as 'parasitoids' and not conventional parasites.

Note: Wasps like these have been introduced many times because of this symbiotic relationship they have to help control caterpillar populations.

Many years ago a scientist Group E plants that produce wrinkled peas the peas from the plants produce new plants that also produce wrinkled peas the scientist concluded that something in the para plan will be transmitted to the next generation this discovery is known as

Answers

Answer:

This discovery is known as heredity.

Explanation:

In the question above, we can see an example of heredity, which is the process where a trait is passed from an ascendant to a descendant. As seen above, the wrinkled seed is a characteristic that was passed on to a plant through its parent, the plant that gave rise to it. The characteristics passed by heredity are transmitted through the continuous transfer of genetic material, present in the DNA. Since the descendants have the DNA of their parents, it is possible that the characteristics are transmitted as the generations advance.
