based on the text how would you define a dominant gene what about a recessive gene
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
why does the oxygen atom in a water molicule have a negative charge
Answer:
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
Geneticists have been working for years to develop higher quality cotton fibers by selectively breeding plants with better fibers. What is a drawback of this selective breeding process?
We can confirm that the drawbacks of selective breeding include increased risk of genetic defects and reduced resistance to immunological threats.
What is selective breeding?This is a breeding method in which specific organisms are bred that contain the desired trait, in order to produce offspring with that specific trait. This brings many downsides in that it reduces genetic variation in the organism, making it more prone to infections and disease, as well as increasing the risk of transmitting a genetic anomaly between breeding cycles.
Therefore, we can confirm that the drawbacks of selective breeding include increased risk of genetic defects and reduced resistance to immunological threats.

Describe the change that occur in the skin to get rid of excess heat.
Answer:
brainly me
Explanation:
When we get too hot: Sweat glands in the skin release more sweat. The sweat evaporates , removing heat energy from the skin. Blood vessels leading to the skin capillaries become wider - they dilate - allowing more blood to flow through the skin, and more heat to be lost.
When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
What do you mean by sweat glands?" Sweat gland is defined by a simple tubular gland of the skin that excretes perspiration, is widely distributed in nearly all parts of the human skin, and consists typically of an epithelial tube extending spirally from a minute pore on the surface of the skin into the dermis or subcutaneous tissues where it ends in a convoluted tuft."
What are the types of sweat glands?There are two types of sweat glands:
eccrineapocrine.What is the main function of sweat gland?"The primary function of sweat glands is to keep the core body temperature at approximately 37 °C by releasing sweat in a hot environment or during physical activity."

Occluded front with points labeled A through D. A: an area of very cold air. B: cold air. C: warm air. D: the ground. The diagram shows an occluded front. Which point identifies the warm air mass in this front? A B C D.
The point that identifies the warm air mass in this front is warm air. So, the correct option is C.
What do you mean by Occluded front?An occluded front may be defined as a composite front formed when a cold front overtakes a warm front and forces it aloft.
The occluded front consists of various points. Each point has a specific property and identity. The temperature of the air is also specific to each point of the occluded front.
Therefore, the point that identifies the warm air mass in this front is warm air.

Plants contain meristems whose major function is to:.
Answer:
Growth in length
Explanation:
Meristems are regions of active cell division within a plant. In general there are two types of meristems: apical meristems and lateral meristems. Apical meristems are located at the tip of the shoot and the root, as well as at the tips of their branches. These meristems occur in all plants and are responsible for growth in length.

Patrick pours 1 cup of lemon juice in a glass. He pours 1 cup of milk in a second glass. The two quids are both left on the same bench for an hour. Patrick then compares the two liquids.which of the following would be different for both liquids ?
The state or phase of the two liquids could be different. Color, volume, and temperature are not necessarily different for both liquids. So, the correct option is B.
What is Liquid?A liquid is one of the three classical states of matter in physics and chemistry – the others being solid and gas. A liquid has a specific volume that never changes yet flows freely and conforms to the shape of its container.
Although the particles in a liquid are relatively close to each other and able to pass each other, intermolecular forces maintain their cohesion. Juice, water, milk and other common liquids contain oils and fats. Although they differ from solids in that they do not have a definite shape, liquids differ from gases in that they have a definite volume.
So, the correct option is B.

The movement of materials from the plasma membrane, through endosomes, and then to lysosomes describes which type of pathway?.
Answer:
Below
Explanation:
The routes that lead inward from the cell surface to lysosomes start with the process of endocytosis, by which cells take up macromolecules, particulate substances, and, in specialized cases, even other cells. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed. One type is called phagocytosis (“cellular eating”), which involves the ingestion of large particles, such as microorganisms or dead cells via large vesicles called phagosomes (generally >250 nm in diameter). The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.

Which organisms are most likely to survive in a population in which disruptive selection is occurring?
organisms that have average traits
organisms that have extreme traits
organisms that have the greatest number of offspring
organisms that are the largest and strongest
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:
B. organisms that have extreme traits
Explanation:
I can confirm this is correct because I just did the test.
