Answer:
what grade
Explanation:
Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.
1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.
2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.
The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.

Mutation may occur in gametes or in body cells. In which cell type is a mutation likely to be source of genetic variation for ?
Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

In photosynthesis, plants use _______ and release ________. *
A. carbon dioxide, oxygen
B. oxygen, carbon dioxide
Answer:
A. carbon dioxide, oxygen
Explanation:
Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:
water + carbon dioxide + light energy —> glucose + oxygen
In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.
Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.

For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.
Answer:
Native species are naturally present in an area. ... Non-native species do not cause environmental or economic harm.

Answer:
They are: substrates, template, primer and enzymes. Four deoxyribonucleotide triphosphates (dNTP's) are required for DNA synthesis (note the only difference between deoxyribonucleotides and ribonucleotides is the absence of an OH group at position 2' on the ribose ring). These are dATP, dGTP, dTTP and dCTP.

Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of the following would make the best project?
Answer:

a video that shows a large river that has penguin populations on both sidesa video that shows penguin species that have different mating dancesa video that shows a penguin that is laying eggsa video that shows penguins in a tidal pool and an open oceanAnswer:
a video that shows penguin species that have different mating dances
The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.
The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.
In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.
Thus, the selected option is correct.
A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
What is Population?A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .
It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time. Population are of three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.
Thus, a video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.

Why does mining have such an impact on the environment? A. Mining only affects the living parts of the environment. B. Because minerals are within the Earth's surface, extraction causes destruction. C. Mining requires the absolute destruction of an area to be cost-effective. D. Areas that are mined can never again sustain plant life. Please select the best answer from the choices provided A B C D
Answer:
B.
Explanation:
The primary environmental effects of mining are on the habitats for wildlife and fisheries, the water cycle, regional temperatures and rainfall patterns, sedimentation, forest loss, and ecological disruption. Thus, option B is correct.
What is the impact of mining on the environment?The effects of mining on the environment include soil, groundwater, and surface water contamination from chemicals produced during mining operations, erosion, sinkhole development, biodiversity loss, and sinkholes.
Mineral extraction from the environment frequently results in imbalances that are harmful to the environment.
Loss of vegetation cover, widespread water body degradation, biodiversity loss, altered land use, increasing social vices and conflicts, high cost of living, and air pollution are some of the negative effects of mining.
