Answer:
species-(i think?)...or maybe family?
Explanation:
well, it's basic genetics. if two organisms of the same species reproduce, a new organism of that species is born. however, if two organisms of different species reproduce, the offspring will be either nonexistent or hybrid. when an offspring is created, it belongs in the same family as its parents.

What will be the frequency of the recessive allele in a population of 100 kangaroos if there are 50 dominant alleles?
0.75
150
0.50
0.25
The frequency of the recessive allele in a population of 100 kangaroos having 50 dominant alleles is 0.75 which is called as the population genetics. So, the correct option is A.
What is Population genetics?Population genetics is defined as the subfield of genetics which deals with genetic differences within and between populations. It is a part of evolutionary biology where the study in this branch of biology investigates phenomena such as adaptation, speciation, and population structure.
Population genetics is described as the estimation of genotypic and allele frequencies in a population. In the given information, there are 100 kangaroos in the population where 50 of which are dominant, i.e. 25% dominant alleles. The frequency of the recessive allele in a population of 100 kangaroos having 50 dominant alleles is 0.75 which is called as the population genetics.
So, the correct option is A.

Why is genetic editing a bad thing?
Answer:
Although it has some good effects it can also harmfully reduce human diversity and increase social inequality majority of genetic editing is pretty bad.
It probably shouldn't even be allowed because it can cause risks to future children, creating new forms of discrimination. This can also make people lose their trust in science technology.
New toxins can be produced, Gene Transfer to Wild or Weedy Relatives, change in Herbicide Use Patterns. There are most Unkown harms yet to be discovered.
Answer:
it messes with genes. genes are important for forming organs and organ system in humans' early stages. Genes define the way we look. If we redefine genes, it may lead to abnormal consequences for humankind.
Genetically editing anything in general could cause serious complications in our world. It's almost like using our precious invention, life as a toy.

Which of the following organisms feed on the detritus found in wetlands? a. Aquatic insects b. Birds c. Reptiles d. Predatory fish Please select the best answer from the choices provided A B C D.
Wetlands are the ecosystem that consists of flooded water and includes swamps and marshes. Aquatic insects feed on the detritus found in the wetlands.
What are detritus and their importance?Dead matter or the organic remains of the plant and animal bodies, and faecal matter are called detritus. They are the litter or the waste that gets decomposed by a certain type of microorganisms.
It is an important aspect of the ecosystem as it serves as a food resource for aquatic insects and organisms. The aquatic insects have various feeding modes and habits and depending on their eating habits they acquire their prey and food source.
Therefore, option A. aquatic insects feed on the detritus found in wetlands.

Which of these is not one of the structures that comprises the outer ear?.
The basilliar membrane not comprises outer ear. The correct option is D.
Thus, The outer ear does not include the basilar membrane. It is a structure inside the cochlea of the inner ear that is essential to hearing because it vibrates in response to sound waves.
The auditory canal, pinna, and eardrum (tympanic membrane).
The cochlea, specifically, contains a component called the basilar membrane, which is located in the inner ear. It is essential to hearing since it affects the outcome. Sound waves vibrate the basilar membrane as they reach the ear.

What is the anammox reaction, and when does it occur in the nitrogen cycle?
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidises ammonium to di-nitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.
The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.
Thus, In order to avoid the buildup of too much nitrogen (such as nitrates and nitrites) in the environment, which can result in water pollution and other ecological issues, denitrification is an essential phase in the nitrogen cycle.
Low oxygen conditions, such as sediments in wetlands, wastewater treatment facilities, and oxygen-depleted regions of oceans, are where anammox bacteria carry out the anammox process.
In the end, this process aids in maintaining the balance of nitrogen in ecosystems and preventing nitrogen pollution by naturally removing excess nitrogen molecules from these habitats.
Thus, The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.

integrated pest management (ipm) is a pest control method founded on the principles of ecology. it involves using several control tactics based on a knowledge of the crop, pests and associated natural enemies. compared to traditional pesticide use on crops, how does a farmer implement ipm and what are the long-term goals?
The overall goal of IPM is to reduce the environmental and health risks of pesticides within social and economic constraints.
Fix: The scope of IPM implementation will continue to change greatly in the future. What began as limited approaches to promote integration of control methods for key pests and provide guidelines for decisions regarding pesticide applications is evolving to an ecologically-based systems approach.
