Answer:
The correct answer is actually D. Sexual reproduction involves both male and female intercourse, while asexual doesn't. In asexual reproduction, the offspring is identical to its one and only parent. Think about sexual reproduction like this. Two parents, and then a child. Are you completely identical to your mom? or your dad? what about both. you can"t be identical to both. Therefore the answer is D.
Which statement best describes the explanatory powers of hypotheses and theories? A hypothesis does not provide an explanation but instead only predicts what may happen. A theory does not provide an explanation but instead only predicts what may happen. The explanation given by a theory is well tested and supported by many observations and hypotheses. The explanation given by a hypothesis is well tested and supported by many observations and theories.
Answer:
. The explanation given by a theory is well tested and supported by many observations and hypotheses.
Explanation:
A theory is a scientific explanation for a given phenomenon. The explanation provided by a theory are usually derived from a well tested hypothesis and experiment.
A hypothesis is a scientific guess of phenomenon. It is upon the hypothesis that most experiments are predicated.
Before a theory is developed from a hypotheses, it must be well tested and proven to be true.

How has ocean exploration increased human understanding of aquatic ecosystems?
Answer: As humans have explored the oceans through time, they have been able to view aquatic organisms in their native habitats. They have been able to witness the interactions of aquatic organisms and learn more about the abiotic factors that govern these ecosystems as well.
Explanation:
Ocean exploration has increased human understanding of aquatic ecosystems through the observation of the interaction of aquatic organisms and their environment.
What is ocean exploration?Ocean exploration is a part of oceanography describing the exploration of ocean surfaces.
The ocean exploration has given humans the opportunity to study aquatic organisms in their natural habitants. These scientist study the interaction of the these aquatic organism with their environment (ecosystem).
Thus, ocean exploration has increased human understanding of aquatic ecosystems through the observation of the interaction of aquatic organisms and their environment.

Answer:
Take in energy
Explanation:
Energy is need by all organism to carry out all functions of life. Energy is defined as the ability to do work.
Every organisms main goal is to find energy which they can use for all of their living processes.
For producers such as plants, they use inorganic substances from the environment to manufacture their own food. Consumers such as animals rely on the organic matter of plants and even other animals to manufacture their food for energy production. Decomposers feed on dead organisms in order to source for energy.Cells without a cell wall will form a_________to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a ________to separate the cytoplasm in cytokinesis
Answer:
Contractile ring, sterols
Explanation:
In cells such as animal cells that lack cell walls, cytokinesis follows the onset of anaphase. A contractile ring composed of actin filaments forms just inside the plasma membrane at the former metaphase plate. The actin filaments pull the equator of the cell inward, forming a fissure.
Examples of bacteria that lack a cell wall are Mycoplasma and L-form bacteria. Mycoplasma is an important cause of disease in animals and is not affected by antibiotic treatments that target cell wall synthesis. Mycoplasma acquire cholesterol from the environment and form sterols to build their cytoplasmic membrane.

Cells without a cell wall will form a furrow to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a cell plate to separate the cytoplasm in cytokinesis, as the cell division of the plant is different from the animal.
What is the significance of the cell wall?It has the structural components of the plant cell that surround the cell membrane of many types of cells and a protective barrier that supports and maintains the shape of the cell, and due to its rigidity, the cleavage furrow does not form but the cell plate is formed.
Hence, cells without a cell wall will form a furrow to separate the cytoplasm in cytokinesis, while cells with a cell wall will form a cell plate to separate the cytoplasm in cytokinesis, as the cell division of the plant is different from the animal.

Maria's body temperature is 98.3 °F on average, but varies from 98.0 to 98.6 °F throughout the day. What are 98.3 °F and 98.0–98.6 °F, respectively, for Maria's body temperature?
A. Negative feedback and positive feedback
B. Positive feedback and negative feedback
C. Normal range and set point
D. Set point and normal range
The temperature of 98.3°F of Maria's body is called as a set point, while the temperature of 98.0-98.6°F is called as normal range.
What do you mean by Temperature?The temperature may be defined as the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
The normal temperature of humans ranges from 98 - 99°F approximately. At this temperature, all the enzymes in the body of human functions properly and effectively. Above this temperature, one shall be considered under a fever state.
Therefore, the temperature of 98.3°F of Maria's body is called as a set point, while the temperature of 98.0-98.6°F is called as normal range.

wrist drop results in an inability to extend the hand at the wrist. which nerve would most likely be affected in this injury
Answer:
The answer to that ir the radial nerve
Explanation:
The distal part of the arm is where the radial nerve is most vulnerable to damage. Entrapment neuropathy might result from it being crushed between the overlaying bone fragments.
What nerve most likely be affected in this injury?Weakness, numbness, and pain are common symptoms of peripheral neuropathy, which develops when the peripheral nerves, which are located outside the brain and spinal cord, are damaged.
These symptoms typically impact the hands and feet. Additionally, it may have an impact on many bodily processes like digestion, urine, and circulation.
Pain, numbness, and/or paresthesia, particularly in the middle finger, index finger, thumb, back of the hand, and/or arm, are signs of radial nerve injury.

The proteins made during transcription are used to make DNA during translation. The RNA made during transcription is used to make proteins during translation. The DNA made during transcription is used to make proteins during translation.
Answer: C, The RNA made during transcription Is used to make proteins during translation.
Explanation:
Just answered this question
The statement that best describes the relationship between transcription and translation is as follows:
The RNA made during transcription is used to make proteins during translation.Thus, the correct option for this question is C.
What is Transcription?Transcription may be defined as the process through which the information encoded within a DNA strand is copied into a new molecule which is known as messenger RNA (mRNA). The process of transcription takes place in the nucleus of the cell.
While translation is the process through which the information encoded within the molecules of messenger mRNA stimulates the production of amino acids during protein synthesis. The process of translation takes place in the cytoplasm of the cell.
Therefore, the RNA (mRNA) made during transcription is utilized in order to make proteins during translation is a statement that best describes the relationship between transcription and translation.
