D.)the offspring can be tall or short

Answer:

Storage

Explanation:

Both lysosomes are vacuoles are cell organelles. Lysosomes are the membrane-bound organelles filled with hydrolytic enzymes. The function of lysosomes is to digest the worn-out part of cells, pathogens, the biological molecules, etc. The presence of various digestive enzymes allows them to digest the worn-out cells, organelles and entered pathogens.

Vacuoles are tonoplast bound organelles that serve to store the metabolites, toxic waste materials, water, ions, electrolytes, etc. They may also store the amino acids and sugars that are not being used immediately by cells.

1. Answer;

-Fungus

Explanation;

-A pioneer species is one which is the first to colonize an area, which can be seen with fungus in the way that spores are quickly spread across large areas.

-Pioneer species are usually lichens and mosses, which can grow on bare rocks. As they grow, the lichens and mosses help break up the rocks to form soil. When these organisms die, they provide nutrients that enrich the developing soil. Over time, seeds of plants land in the new soil and begin to grow.

2. Answer;

The statement above is true

Explanation;

-Secondary succession can happen after primary succession or independently of primary succession.

-Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation by forest fire, tsunami, flood, or an abandoned field.

-Secondary succession may occur independently, but the stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.

3. Answer;

A. It occurs in ecosystems without soil.

Explanation;

-Secondary succession refers to the process that happens after a disruptive event, reducing the population of species in an ecosystem. As opposed to primary succession that occurs in an ecosystem lacking soil, secondary succession happens on preexisting soil.

-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.

Grass is an example of a pioneer species, so option d is correct. The second statement is True. Secondary succession can happen after primary succession or independently of primary succession. Secondary succession reduces the number of species in an ecosystem thus the answer is (C).

Hardy species called pioneer species are the first to establish themselves in once-biodiverse steady-state ecosystems. Lichens, fungi, bacteria, fireweed, grasses, alder, and willow are examples of pioneer species.

In primary succession, living organisms first occupy newly exposed or newly created rock. In secondary succession, a previously inhabited area is disturbed, disrupted, and then recolonized as a result of the disturbance.

In third question, among all the given options only option (c), "it reduces the number of species in an ecosystem" is not true.

Before secondary succession starts, a variety of species will already be present in the ecosystem and new complex plants and animals move in as the ecosystem develops, bringing with them new species. so it will increase the number of species in an ecosystem.

Therefore, in question 1st, option d is right, in question 2nd, the given statement is true, and in 3rd, option c is right.

C) It reduces the number of species in an ecosystem.

D) It is initiated by a disruptive event.

Answer:

Explanation:

Just believe in me

Answer:

ER is found in both animals and plants

Explanation:

the endoplasmic reticulum is found in both cells of animals and plants

Answer:

Gregor Mendel was the first biologist who applied the principles of mathematics to study the pattern of inheritance in Biology. This led to the criticism and not an acceptance of his work at his time but after his death, his work was widely recognised as:

1. Mendel's work provided each and every detail of the experiment from species to a number of offsprings and traits.

2. His experiments included a large sample size which reduced the chances of error in his results.

3. He studied the pattern of inheritance for distinguishing traits.

4. His ideas and explanation on experiments were logical which were supported by the scientists later.

These logical ideas later helped recognize his work and he became the Father of Genetics.
