Insulin is a hormone that travels through the blood and helps regulate blood sugar levels. Which best describes how insulin travels in the blood?
in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells
Answer:
A:in the plasma
Explanation:
Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.
What is insulin?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.

Determine whether each activity impacts land resources in a positive or negative way. Drag each term to the correct
category.
desertification
Positive Impacts
Negative impacts
reforestation
laws and regulation
habitat restoration
erosion
urbanization
deforestation
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.

g you are given three bacterial cultures: Pseudomonas aeruginosa, Shigella sonnei & Escherichia coli and you carry out a Triple Sugar Iron (TSI) assay for each 1. The tube for P. aeruginosa shows a pink butt, pink slant with no gaps or breaks in the medium and no black precipitate 2. The tube for S. sonnei shows a yellow butt, pink slant with no gaps or breaks in the medium and no black precipitate 3. The tube for E. coli shows a yellow butt, yellow slant with no gaps or breaks in the medium and no black precipitate Which of these organism can reduce glucose but not lactose and/or sucrose?
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.

The size of the iris and pupil can change size. If you walked from a bright room into a dark room, what would happen to the size of the iris and pupil?
Group of answer choices
the iris and pupil would not change size
the iris would get smaller, the pupil would get bigger.
the iris would get smaller, the pupil would get smaller
the iris would get bigger, the pupil would get smaller
the iris would get bigger, the pupil would get bigger
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.

How would you describe the movement of the sun over 30 minutes?
Answer:
The Earth rotates from the west to east. The Sun does not rotate around the Earth, in Thirty minutes. the sun would appear to be in a different part of the sky, and that is because of the Earth's rotation.
Explanation:
Answer:
The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates. The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.
