Which statement best describes Mendel's law of dominance?
O
A. Each parent of an offspring contributes two factors for each of the
offspring's traits.
B. The separation of two factors for one trait will always affect the
separation of another trait's factors.
O
C. Inherited traits are controlled by two factors that separate during
reproduction.
D. Only one of the two factors that control a trait is expressed when
both types of factors are present.
Only one of the two factors that control a trait is expressed when both types of factors are present best describes Mendel's law of dominance. Thus option D is correct.
what is Mendel's law?
According to Mendel’s Law of Dominance When an organism is mixture of heterogeneous trait, it expresses allele which are dominant, here the dominant trait always masks the recessive trait.
The trait is present in the form of two allele and one allele is dominant over the other allele which is recessive.
The dominant allele contributes exclusively to the phenotype of the offspring and Dominance can also be described as when one of the two alleles is non-functional means it does not produce a functional protein.
The recessive trait will be expressed only when both the allele are present in homozygous form from both parents.
Thus option D is correct.

what would happen if a new predator was introduced into the ecosystem that only ate mice ? Would the mouse population be lowered ?What else would happen because of this
Answer:
The mice population would be lowered, and that predator could be a prey to other predators in that environment.
Explanation:
The introduction of new predator has both positive as well as negative effects on the ecosystem and environment.
What happen when the predator in introduced in an ecosystem?If a new predator was introduced into the ecosystem that only ate mice so this results in the reduction of population of mice which leads to the disturbance of the ecosystem.

Answer:
D. To show condensation, you add energy to change water vapor into liquid water; to show evaporation, you add energy to change liquid water into water vapor.
When condensation occurs, gas turns to liquid, and when evaporation occurs, liquid turns to gas.
B. could also be correct, but D. seems to be the better fit.
Answer:
To show condensation , you must decrease the temperature within the cycle ; to show evaporation , you must increase the temperature .
Explanation:
Condensation : condensation is nothing but the change of water vapour into liquid water . it happens when the water vapour reaches from a hot area to a cold area . for instance ~ when you pour hot tea in a cup and cover it with a plate. after few seconds you would see droplets of water there . this means that the water vapour which was in liquid form , when touched the cold surface of plate , it changed into liquid water .
Evaporation : It is the conversion of hot liquid into water vapour . just reverse of above phenomena .

Normal blood cells slide easily through narrow blood vessels. In sickle cell disease many red blood cells change to a crescent shape like a slender moon Crescent-shaped blood cells cause blockages in blood vessels These blockages decrease the transport of oxygen People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body Some people have one sickle cell gene and one normal gene They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the method of reproduction in humans result in people getting one copy of a sickle cell gene and one copy normal gene? Describe the process
Answer:
Explanation:
The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.
The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent during copulation giving rise to an individual that is heterozygous for the trait
For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.

Compare and contrast pollution caused by irrigation and by pesticides.
Pesticide pollution and irrigation pollution have different characteristics, but both have the potential to have negative effects on the ecosystem.
Here is a side-by-side comparison of the two:
Pesticide usage and irrigation both have the potential to contaminate water. Excessive irrigation can result in the contamination of nutrients in water bodies due to the leaching of pesticides and fertilisers.
Both pesticides and irrigation can have a negative impact on ecosystems. Excessive irrigation water use can harm aquatic habitats and deplete water supplies.
Pollution sources: Irrigation is a major cause of pollution due to the excessive water use and subsequent discharge of nutrients, silt, and fertilisers.
Pesticides, on the other hand, are chemical compounds created especially to manage pests and have the potential to pollute the environment directly through runoff, spray drift, or persistence in the soil.
Management and Regulation: Irrigation and pesticides are managed and regulated in different ways. Policies for managing water resources and conservation measures can be used to control irrigation practices.
Contrarily, the use of pesticides is subject to stricter laws and oversight to guarantee correct application, handling, and mitigation of side effects.
Thus, this is the comparison and difference between pollution caused by irrigation and by pesticides.

What is a Schwarzchild radius and what does it have to do with a black hole
Answer:
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole
Explanation:
The Schwarzschild radius define the “size” of a black hole. Theorists believe that all the “stuff” inside a black hole collapses into a singularity, an infinitely small and infinitely dense point well inside the boundary defined by the Schwarzschild radius.

Consider the food web seen here. One member, the northern spotted owl, lives in cavities of trees in old-growth forests. Old
growth forests contain trees that are more than 200 years old and have not been cut, pruned, or managed. Imagine that these
forests have been heavily logged, Predict the outcome on this food web if the habitat of the owl is removed
AY
The food web will collapse without this top-level consumer present
B)
The niche filled by the owl will be filled by other predators like the hawk
and fox
The niche filled by the owl will be empty. The other animals within the
food web will grow unchecked.
Without the owl present, the empty niche will result in an overpopulation
of hawks. Eventually the lower-level consumers will disappear
DY
Answer:
I'm pretty sure it is the third option: The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
Explanation:
The owl is a predator animal. As it hunts small prey, it keeps the population of those prey animals stable. If the owl is taken out of the habitat, then the population of the prey animals it used to hunt will grow out of control.
The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
What is a food web?All the food networks in a single ecosystem make it into a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the environment. A food web is made up of all the linked and overlapping food systems in an ecosystem.
The trophic levels are divisions into which organisms in food webs are categorized. These levels can be roughly categorized as producers (first trophic level), consumers (second trophic level), and decomposers (final trophic level).
The first trophic level is producers. Producers often referred to as autotrophs, produce all of their own food and do not rely on any other living thing for sustenance. The majority of autotrophs convert sunlight, carbon dioxide, and water into food (a nutrient called glucose) through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live near active volcanoes make their own food by using sulfur rather than carbon dioxide. Chemosynthesis is the name of this process.
Therefore, The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
