Answer:
Explanation:
A gamete is a haploid reproductive cell that fuses with another gamete of opposite strain to form a diploid
zygote.
A zygote is a cell formed by the fusion of the male and female gamete before it undergoes division.
gametes are haploid while a zygote is diploid.
There is exchange of genetic material during sexual reproduction and fusion of gametes. Meiosis is also involved.
The opposite occurs in asexual reproduction and mitosis is involved instead.
Asexual reproduction is common in prokaryotes eg bacteria.

bloaccumulation
risk assessment
toxicity
biomagnification
Answer:
bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.

Land warms up faster than the sea.
A. True
B. False
Answer: Solar radiation is absorbed more by land surfaces than by water. Solar radiation from its surface is reflected from water and returned to the environment. Keeping the land surface warm, as well as the vegetation for energy, because land absorbs much more solar radiation. The warmer the surface of land, the quicker it warms.

4) What factors influence the circulation of the Earth's atmosphere,
thereby producing our weather?
The uneven heating of the earth's surface is one of the main variables affecting the circulation of the atmosphere globally along with seasonal variations in precipitation and temperature and Earth turning on its axis.
What is weather?The state of the atmosphere is referred to as the weather, and can be described in a number of different ways, including the degree to which it is hot or cold, wet or dry, quiet or stormy, clear or cloudy. The troposphere, the lowest layer of the Earth's atmosphere, is where the majority of meteorological events take place. The stratosphere is the next layer up from the troposphere. The term "weather" is used to describe the temperature, precipitation, and other characteristics of the atmosphere on a day-to-day basis.
Variations in air pressure, temperature, and moisture from one location to another are the primary contributors to a day's weather. These disparities can be attributed to the fact that the angle at which the Sun is positioned at any given location varies with latitude. The vast temperature difference between the polar and tropical air masses is what gives rise to the biggest scale atmospheric circulations.

Events that take place in a biome are shown in the diagram below.
What information is represented in the diagram?
A
Respiration and photosynthesis are connected.
B
Transpiration is related to the nitrogen level in bacteria.
C
Predators and their prey are involved in many interactions.
D
Decomposers release a material that is utilized by other organisms.
Answer:
D - Decomposers release a material that is utilized by other organisms.
Explanation:
The cycle represented is the nitrogen cycle. In it bacteria of decay will break down or decompose plant and animal remains and wastes.
The information represented in the diagram is that decomposers release a material that is utilized by other organisms. So, the correct option is D.
What do you mean by Biome?A Biome may be defined as a very large area that is characterized by a particular type of vegetation.
The diagram represented here defines the nitrogen cycling in the atmosphere. Decomposers convert the dead and decaying organic matter into inorganic ones which are easily consumable for the plants.
Decomposers directly do not release any material but they convert the material into a specific form which is then utilized by other organisms.
Therefore, the correct option for this question is D.

Scientific study of the population cycles of the snowshoe hare and its predator, the lynx, has revealed that ________. Question 9 options: A) predation is the dominant factor affecting prey population cycling B) hares and lynx are so mutually dependent that each species cannot survive without the other C) the hare population is r-selected and the lynx population is K-selected D) both hare and lynx population sizes are affected mainly by abiotic factors
Answer:
A) predation is the dominant factor affecting prey population cycling
Explanation:
Predation is a type of interaction between species where one species called ‘predator’ uses another species, the ‘prey’, as a source of food. Within an ecosystem, the number of predators and prey may vary over time in cycles of time (in these cases, the population cycles of both species are closely linked). In consequence, predation is a density-dependent factor. In the case of the snowshoe hare and its predator, the lynx, when the number of predators is too high, the number of prey drastically decreases. Subsequently, this leads to the decrease of predators that leave their home range (they don’t have enough food to survive), thereby the snowshoe hare population increases again until the peak of the population cycle (carrying capacity), and so successively.
