What additional restriction enzyme would be used to cut out another gene flanked by a different restriction site?

Answers

Answer:

Explanation:

Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.

How is phosphorus NOT returned to the abiotic portion of the environment?
A. Death and
decomposition
B.animal waste
C. Fertilizer use
D.acid rain

Answers

Answer:

D) acid rain

Explanation:

Phosphorus is not returned to the abiotic portion of the environment through d. acid rain.

Abiotic portion of the environment are the nonliving components such as soil, water, or air.

Phosphorus is an essential element in any ecosystem that supports life and the functioning of the ecosystem. Phosphorus is used and returned into an ecosystem through various means in the phosphorus cycle.

Animals and plants are composed of phosphorus. When they die and decompose, phosphorus is returned to the aortic portion of the environment. Also, it is returned via the waste of animals.

Fertilizers containing phosphorus also add phosphorus back to the abiotic portion of the environment.

Acid rain occurs when Sulphur dioxide and nitrogen oxides mix and interact with oxygen and water in the atmosphere to form acidic compounds released as precipitation to the environment.

Therefore, phosphorus is NOT returned to the abiotic portion of the environment through d. acid rain.

Briefly explain the three clues that suggest that bacteria are an evolutionary success story

Answers

Answer:

The evolutionary success of this group results from its 1- small size, 2- simplicity and 3- fast reproduction rate

Explanation:

Bacteria are evolutionarily successful organisms that makeup about 15 percent of all biomass on Earth, and they occupy almost all habitats in nature. The small size of these unicellular organisms facilitates the exchange of nutrients and waste products with the surrounding environment. In addition, the relative simplicity of bacteria also facilitates the assembly of cell structures as well as a fast reproduction rate by the fast division of single cells. All these features are critical in order to understand the rapid evolution rate observed in this group.

24. Name two types of pathways that help a body maintain homeostasis, and an example of each.

B

I

U

Font Family

Answers

Answer:

See the answer below

Explanation:

Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways

Negative feedbacksPositive feedbacks

Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat

Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

The lightbulb part of the circuit is consider the "load"

What is simple circuit?

A simple circuit is a circuit that contains the three basic components needed for an electric circuit to function. The three basic components are a source of voltage, a conductive path, and a resistor.

When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

Hence, option C is correct.

If a student tested the bubbles collected in the test tube what would they find they are made of and how do you know?

Answers

Hello. This question is incomplete. The full question is:

A student prepared two beakers with identical sprigs of a water plant as shown below. She placed Beaker A in the shade and the Beaker B beside a fluorescent lamp. She then systematically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.  

If the student later tested the bubbles collected in the test tube, What would she find they are made of?

Answer:

oxygen

Explanation:

The bubbles are oxygen and we can say that because this is the gas that plants release through photosynthesis. In this case, we can also confirm that the plant that was exposed to fluorescent light, showed more bubbles than the other plant, since the light allowed the photosynthetic rate of this plant to be higher, releasing more oxygen to the environment.

POSSIBLE POINTS: 2 A student wondered if different types of plants would produce different amounts of oxygen. A pea plant, a fern, and a cactus were growing in equal-sized containers with equal amounts of soil. The student measured the amount of oxygen produced by each. Identify one factor (other than the size of the container and the amount of soil) that should be held constant in this experiment. Explain why this variable needs to be held constant. ​

Answers

Answer:

The correct answer would be - the amount of water they get.

Explanation:

In any research or study, there are some variables other than the independent variable that can affect any experiment directly or directly. To avoid such conditions these variables are held constant.

In this case, the production of oxygen can be affected in all three plants due to various variables also such as the amount of soil, size of the container, amount of water all three different plant gets, and others.

Thus, the correct answer would be - the amount of water should be held constant.
