Scientist often referred to mushrooms as the dark matter of biology because we don't know much about them. Mushrooms are not pla

stiks02 [169]

Answer:

Mushrooms and plants all need energy to grow. But the sources of their energy differs.

Explanation:

Sun is the ultimate source of energy for any living organisms to grow and make their food. While plants takes energy from the sun directly and make their food, while the mushrooms which is not a plant does not take energy from the sun directly.

Mushrooms utilizes the energies which is collected by the different organism which collects their energy from the sun such as organisms like the bacteria and plants. Mushrooms grow well in darkness as darkness helps to retain moisture. Mushrooms does not have chlorophyll to make food.

Plants have chlorophyll. And they direct absorb energy from the sun light to make their own food.

A 2-year-old swallowed watch batteries. Following ingestion, kidney function was impaired, and the heart began to fail. Which of

kvv77 [185]

Answer:

Coagulative necrosis

Explanation:

When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .

Consider the evidence that explains how physical separation of two populations of a species can cause speciation. What effect do

Tom [10]

Answer:

Interruption in the genetic flow between separated groups

The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
Genetic divergence by natural selection and reproductive isolation
Prezigotic isolation mechanisms

Explanation:

Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

The process of allopatric speciation involves different steps that affect organisms:

The emergence of the barrier.
Interruption in the genetic interchange
The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.
