False, it is only represented by one class: Crinoidea (sea lilies).

Explanation:

Echinoderms (phylum Echinodermata) are marine organisms that comprises more than 6,000 species. These animals are deuterostomes that are differentiated to have an ambulacral  vascular system and a pentameric symmetry. Echinoderms are divided in the following classes: 1- Ophiuroidea (snake stars), 2-Asteroidea (sea stars), 3-Crinoidea (sea lilies), 4-Holothuroidea (sea cucumbers) and 5-Echinoidea (sea urchins), which can be easily distinguished  by anatomical and ecological characteristics.

Answer:

it should be natural selection but im not too sure...

Explanation:

Answer:

The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

Answer:

2.The human circular system does pretty much the

same thing as a plant but the plant can also reproduce oxygen. The

human needs air so does a plant to live and make more air. The

human needs food so does a plant to stay healthy. The human needs

to drink water to live too so does the plant to stay alive

otherwise it will rot and fall apart.

Answer:

the smallest particle of a chemical element that can exist.

The smallest  and basic subunit of a matter is called as Atom.

Atoms are the smallest and basic units of  matter which has three subatomic particles such as positively charged protons, neutral Neutrons form nucleus.

A negatively charged electron which surround the nucleus of the atom.  

In nucleus equal number of protons and neutrons, atomic number is the number of protons and atomic mass is made of the sum of protons and neutrons.

The nucleus does not change during chemical reactions, only in nuclear reactions it will change.

Smaller electrons orbit the nucleus participate in chemical reactions .

Due to less nutrients and oxygen, these cells die as they are pushed towards the surface of our skin.

Answer:

Test Tube 2 (S. sonnei)

Explanation:

Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.

The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.

When the bacteria ferment any of the three sugar, the medium turns yellow.

In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.

In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.

In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.

Thus, test tube 2 (S. sonnei) is the correct answer.

Answer:

(1) cellular respiration, (2) photosynthesis

Explanation:

Answer:

A:in the plasma

Explanation:

Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.

Insulin is a hormone that is released by β-cells of the pancreas. It controls the amount of glucose in our bodies. It converts glucose into glycogen and then this glycogen is stored in the liver, and whenever the glucose level reduces in the blood, then this stored glycogen is converted into glucose. It also helps in breaking fat and protein for energy.

Insulin is a very important hormone for the regulation of glucose in the blood. A deficiency of insulin occurs when the immune system attacks islets and it causes diabetes, in this disease blood sugar level increases

.

Insulin flows in the blood through plasma. Therefore, option A is correct.

The correct answer is B. The iris would get smaller, the pupil would get bigger.

Explanation

The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.

Answer:C2H6)

Explanation:

Answer:

C2H6O

Explanation:

Answer: Mutualistic.

Explanation:

Answer:

desertification - negative impacts

Reforestation - positive impacts

laws and regulation - positive/negative impacts

habitat restoration - positive impacts

erosion - negative impacts

Urbanization - negative impacts

deforestation - negative impacts

Explanation:

Desertification is a process in which productive lands become a dry, unproductive one as a result of humans or natural activities such as drought, deforestation, etc. It impacts land resources negatively in that land generally becomes unproductive and unsupportive to other lives.

Reforestation is a process of artificially creating forest where one has been removed or where none existed before. It involves the planting of trees and leads to the creation of new land resources such as habitats, water sheds, etc.

Laws and regulations can impact land resources either positively or negatively depending on the type of laws. Laws that promote land conservation positively impact land resources while those that promote the wanton use of lands negative impact land resources.

Habitat restoration refers to activities geared towards restoring habitats of organisms that have been degraded by human or natural activities. Habitat restoration positively impacts land resources as natural processes are directly impacted positively.

Erosion involves the removal of topmost layer of soils by running water or wind. It negatively impacts land resources by rendering land unproductive impacting the protective nature of soil on other resources such as watershed, etc.

Urbanization refers to the process of actively developing an area vis a vis the construction of more buildings and other infrastructures to make a place more urban. Land resources are negatively impacted in the process as most often requires the conversion of lands to non-forested uses.

Deforestation is the removal of forest layers for non-forest uses. It negatively impacts land resources such as habitat removal, lower biological diversity, protection of water sheds etc.
