What are some nonlethal solutions to the problem of wolves attacking cattle and sheep?
Answer:Fences, loud alarms, and keeping animals in a safe space
Explanation:
describe the difference between covalent and ionic bonds. give one example of each
Answer:
Actually, a covalent bond is formed between two non-metals. Electrons are shared between the two atoms in order for them to achieve a full outer shell. Covalent compounds do not conduct electricity. An ionic bond is formed between a mental and a non-metal. Electrons are transferred from the metal atoms to the non-mental atoms to form ions. Ionic compounds conduct electricity when dissolved.
Research since Mendel's time has established that the law of segregation of genes during gamete formation Research since Mendel's time has established that the law of segregation of genes during gamete formation applies to all sexually reproducing organisms. applies to all asexually reproducing organisms. applies to all forms of life.
Answer:
applies to all sexually reproducing organisms.
Explanation:
The law of segregation of genes applies to all sexually reproducing organisms because segregation occurs in the gametes. The Mendelian trait alleles may be dominant or recessive and they will passed down from parent to child. In plants, for example, the color trait of the flower will depend on the type of allele inherited by the offspring. Each parent plant transfers one of the alleles to their offspring and the dominant allele shows itself in the appearance.
Answer:
The correct answer is: applies to all sexually reproducing organisms.
Explanation:
Mendel's laws of segregation are a group of basic rules that explain how gene transmission (inheritance) occurs from parents to children in every species that reproduces sexually and constitute the foundation of Genetics.
Diploid species, such as rats or humans, for example, possess two sets of chromosomes, one that comes from our mother and one that comes from our father. To make the perpetuation of species possible, diploid individuals produce, through a process called Meiosis, sex cells called gametes - which contain only one set of chromosomes (each chromosome will have only one copy of each gene) that will add up to another set of chromosomes when they encounter another gamete from the opposite sex.
Each chromosome will have specific genes, and these genes can manifest in different variations that are called alleles. Depending on the alleles present in the chromosomes that we inherited from our mother and father, the gene will express itself in one way or another. This is thanks to the law of segregation that states that each gamete randomly receives one allele for each gene.
Individuals that reproduce asexually do not produce gametes; their progeny is identical to themselves, This is why Mendel's laws of segregation only apply to species that reproduce sexually and not all living organisms.

What are the reactants for cellular respiration? (1 point)
Answer:
In cellular respiration oxygen and glucose are both reactants. Cellular respiration is mostly based on ATP; carbon dioxide and water from waste products.
Explanation:
Glucose and oxygen are reactive to ATP in cellular breathing. The by-products are water and carbon dioxide. Glycolysis (anaerobic process), a cancer cycle, and oxidative phosphorylation are three steps of aerobic cell breathing.
CO2 + Oxygen CO2 + H 2O C6H12O6 + 6O2 +Water Glucose (sugar), Sugar Cellular breathing, or aerobic breathing is a sequence of chemical processes which, in the presence of oxygen, start with sugar reactants and create carbon dioxide and water as waste products.

Consider a simple scenario: A bird species lives on a tiny island in the Pacific Ocean. Due to a single mutation some individuals start breeding in the fall and not in the spring, like the other individuals of this species. As a result, these two populations (spring and fall breeders) living together evolve into two separate species. This is an example of: Group of answer choices
Answer:
Reproductive barrier ⇒ isolation mechanism ⇒ seasonal or temporal isolation.
Explanation:
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, and the postzygotic mechanism avoids the zygote to develop and reach the adult stage.
Among the prezygotic mechanisms, we might find behavioral isolation, seasonal or temporal isolation, sexual isolation, gamete incompatibility.
Seasonal or temporal isolation occurs when individuals of different species occupy the same area, have the same reproductive behavior, and their gametes are compatible, but they do not get to mate because their reproductive seasons differ.
In the exposed example, after the speciation process, both bird species living together are not capable of mating because one of the species mates in the spring and the other one breeds in fall.
The reproductive barrier is the process in which two species are not able to reproduce due to the variation in the species.
Reproductive barrier isolation has two types:-
Mechanism seasonalTemporal isolation.
Seasonal or temporal isolation happens when individuals of different species live in the same area, have the same reproductive behavior, and their gametes are compatible,
The birds given in the question are not able to reproduce due to seasonal variation. In the speciation process, both bird species living together are not capable of mating because one of the species mates in the spring and the other one breeds in fall.

what are the five layers of the atmosphere? Explain each layer.
Answer:
There is (from closest to the surface of the Earth) ...
Explanation:
Troposphere: the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere: the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere: the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere: the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Exosphere: the outermost region of a planet's atmosphere.

what represents the control group
Answer:
which control group are you talking about?
Answer:
A control group shall be the subject group without treatment or standard treatment. The Control group shall be the subject group. Nothing would be compared to the treatment group without the control group. Where statistics refer to "X times higher" the difference in measures between the treatment group and the control group is referred to. A basic feature in the experiment is the control group.
Explanation:
Exactly the same conditions as therapy groups will apply to the control group. This makes it possible to measure only the effects produced by the variable. For example, in a plant study, each plant would ideally be in the same space, under the same conditions of light and air.
Control groups are also used when medicines are tested on humans. While control groups were only considered to be good science, drug trials found an interesting phenomenon. Control groups are frequently found in drug studies in people who have a disease or ailment but are not tested for the medicine.
A fake medicine is given to the control group, and patients begin to see findings. This is called placebo by scientists and is still mainly unexplained. Some scientists suggested that people improve simply because they thought they would get better, but this theory is not tested.
Which of these could cause the amount of carbon dioxide in the atmosphere to decrease?
Answer:
An increase in the number of producers.
Explanation:
Producers/plants absorb carbon dioxide during photosynthesis and give off oxygen.Therefore to decrease the carbon dioxide in the air,we would have to plant more trees.
Have a nice day.
The percentage of carbon dioxide in the atmosphere should be 0.04% an increase in this amount can adversely affect the environment. Its amount can be decreased by increasing producers.
What is carbon cycle?Carbon cycle is the process of circulating carbon atoms from atmosphere to Earth and then again to atmosphere.
Carbon dioxide is increased in atmosphere by increasing respiration, increasing amount of decomposers, use of fossil fuels.
The way to decrease the concentration of carbon dioxide in atmosphere is by increasing number of producers.
Producers makes their food by absorbing carbon dioxide and release oxygen as a byproduct, hence decreasing the concentration of carbon dioxide.
Thus, the correct answer is D.

Explanation:
One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were all type AB?
Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.

What are antibiotics and when can they not be used
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.
Answer:
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

. Traits cannot be good or bad, their effect on the success of a creature depends on the environment and circumstances.
. A mutation in an individual is evolution.
. The process of evolution is random, but the selection of genes/traits is not.
. An organism that is more complex is more evolved.
