The correct statement is liver cells possess transcriptional activators that are different from those of lens cells.

Transcriptional activators are specific protein sequences capable of activating gene expression.

These transcription factors (transcriptional activators) act to regulate gene expression in target cells.

Transcriptional activators are factors that enable the expression of certain genes in particular cell types.

Warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.

Nasal mucous membranes are lined with small blood vessels that help to warm as well as humidify the air you breathe. They are also lined with cilia which is a tiny hair-like structures that help to trap the debris that you breathe in during inhalation.

So we can conclude that warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.

Selective pressures( Predators, less food etc. ) will cause the less fit variation of a species to decrease in population, causing them not to be able to reproduce. The more fit variation would be able to reproduce more so that over time, the individuals in the species will have the features of the more fit variation.

Explanation:

The statement that correctly describes a feature of the rock cycle is: Rocks change from one type to another. In the rock cycle, rocks can be transformed through different processes. The correct option is B.

The rock cycle is a process by which rocks are transformed from one type to another through a series of physical, chemical, and biological processes. The rock cycle involves the transformation of igneous, sedimentary, and metamorphic rocks, and these three types of rocks are related to one another.

The process of the rock cycle is continuous and does not follow a specific order as rocks can change from one type to another in any direction. The rock cycle is essential to the formation and recycling of rocks on Earth.

Therefore, the correct option is B.

The section of DNA being used to make the strand of mRNA is known as the transcription unit.

Transcription units are base sequences of DNA that make up a single mRNA molecule during the process of transcription.

During gene expression, genes are first transcribed to genetic codes in mRNA molecules before being translated to their respective proteins.

Each unit of transcription represents a gene along with non-coding base sequences in DNAs, otherwise known as introns.

Explanation:

their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.

Gravity influenced the growth of germinating corn seeds by providing the directional cue for root growth and promoting proper orientation of the plant.

Gravity plays a crucial role in plant growth and development, particularly during the germination of seeds. When a germinating corn seed is placed in a gravitational field, gravity acts as a guidance mechanism for the growing seedling.

In response to gravity, the root of the germinating seed grows in a downward direction, a process known as gravitropism or geotropism. This downward growth of the root is called positive gravitropism. The root responds to the gravity stimulus by redistributing auxin, a plant hormone, towards the lower side of the root. This causes cells on the lower side of the root to elongate more than cells on the upper side, leading to downward growth. The downward growth of the root helps anchor the plant in the soil and facilitates water and nutrient absorption from the ground.

Simultaneously, gravity also influences the shoot of the germinating corn seed. The shoot exhibits negative gravitropism, where it grows upward against the force of gravity. This upward growth is counterbalanced by the downward growth of the root, allowing the plant to establish proper orientation.

Without the presence of gravity, the germinating corn seeds would not be able to establish the proper orientation and direction of growth. The root may not grow downward, leading to irregular and inefficient water and nutrient absorption. The shoot may not grow upward, resulting in an abnormal and compromised overall plant structure.

Therefore, gravity serves as a crucial external factor that guides the growth of germinating corn seeds, ensuring proper root development, anchorage, and shoot orientation for successful plant growth.

Answer:

Organisms that have extreme traits.

Explanation:

Disruptive selection is a specific type of natural selection that describes changes in population genetics. In disruptive selection, both extreme values for a trait are favored over intermediate values. As a result, the population is divided into two distinct groups and the variance of the trait increases.

Answer:

Veins arteries and capillaries

The structures in the human body that carry out some of the same function as xylem and phloem are veins, arteries, and capillaries.

Xylem and phloem are the vascular tissues that transport water, minerals, and food from the roots to the leaves and from the leaves to the roots respectively.

Xylem and phloem represent homology with the veins and arteries. Veins carry blood back towards your heart, while arteries carry blood away from your heart.

Capillaries are blood vessels that carry the oxygen and nutrients from the blood and transport them into the tissues and organs. It also requires the elimination of the waste products away from your tissues.

Answer:

sensory, motor, and interneurons.

Explanation:

For neurons in the brain, at least, this isn't an easy question to answer. For the spinal cord though, we can say that there are three types of neuronssensory, motor, and interneurons.

Answer:

Afferent "Sensory" Neuron

Interneuron "Associative Neuron"

Efferent "Motor" Neuron

Explanation:

The Afferent Neuron or Sensory Neuron receives information from the sensory receptors and carries the impulse from the sense receptors to the central nervous system. In this example the touch receptors in the skin are relaying information through the Afferent "Sensory" Neuron from the environment to the spinal cord.

The Interneuron or the Associative neuron is the transfer station or the decision making neuron. In the case of the reflex arc the Interneuron would make a decision to respond or not respond based upon the intensity of the stimulus.

The Efferent Neuron of Motor Neuron would then return the impulse back to the muscle or gland that would need to respond.

The sun is a star, this means the sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
