What are genes ?
Genes are segments of DNA which are located on chromosomes contain the information's for protein production, in humans 25,000 genes are present, which exist in more than one form.
The alternative forms of gene which are are expressed as a character in a species are called alleles and they are typically present as two alleles for a given trait.
Alleles gives distinct traits that can be passed on from parents to offspring known as Mendel's law of segregation.
In humans, alleles of a gene come in pairs, one on each chromosome, If both the alleles of a particular gene are the same, the individual is called as homozygous, If they are different the organism is described as heterozygous for that gene.

Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.

Answer:
Meiosis
Explanation:
Because Meiosis creates cells that are destined to be gametes (reproductive cells), this reduction in chromosome number is critical without it. The union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes

Do fitness (as used in biology) and survival have the same meaning? Why or why not?
Answer:
No
Explanation:
They are not the same. The fittest individual is not necessarily the strongest, fastest, or biggest. Fitness also applies to the ability to find a mate and produce offspring. Survival is the form that an individual will leave the most copies of itself in the subsequent generations

The nucleus is a large, oval organelle in a cell. It contains the cell’s genetic material in the form of
__________and controls many of the cell’s activities.
Answer:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
Plan a controlled experiment to investigate how much the temperature of a large mass and a small mass of cold water changes when hot water is added. Assume you have access to water, containers, ice, a heat source, a scale, and thermometers. Summarize your experiment in a few sentences.
Plz help >` '
Answer:
The small mass got hotter than the large mass. I think the main reason is because the smaller the mass is, the less time it takes to heat up.The larger mass took a while to heat up, while the smaller mass heated up quickly.
Explanation:
This is what I put, please mark me as Brainliest :)
Good Luck! <3
Answer: The small mass heated up more quickly than the large mass. The main explanation, in my opinion, is that heat-up times are shorter the smaller the mass is. The smaller mass warmed up instantly while the larger mass took a while.

Explanation:
An ice age is a period in which large areas of Earth are covered in ice. Throughout its history, Earth has experienced at least five such ice ages.
Ice is white in color, so it reflects most of the sunlight it receives. Imagine that an ice age were to happen again on Earth. Which statement
best explains how Earth's temperature would be affected?
Refer to the below image for assistance.
Answer:
A
Explanation:
The earth would be covered with ice, therefore there would be no soil, water, or rocks to absorb the sunlight.

define homologous structure in YOUR OWN WORDS
Answer:Homologous structures are similar structures that evolved from a common ancestor. Learning Objectives. Describe the connection between evolution and the appearance of homologous structures.
Explanation:A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.

Explanation:
You have been tracking an adult female otter who weighs 25 kg. How many kilocalories must she consume each day to maintain her body weight?
Answer: 62.5 kilocalories
Explanation:
Otters are a subfamily of carnivorous mammals which consume a variety of animals such as amphibians, crustaceans, fish, snails, water insects, worms, birds, turtles, frogs and aquatic invertebrates (insects). They are great swimmers which helps them look for food, and they can close their nostrils being able to stay underwater for up to 4 minutes.
A calory is an unit of measurement of the energy found in food which is defined as the unit of thermal energy equivalent to the amount of heat needed to raise the temperature of 1 gram of water by 1 degree Celsius. For example, if a certain food provides 300 calories, this is the energy that the body could receive when consuming it.
To maintain its weight, the female otter must consume 250 calories per kilogram of body weight per day. So if the otter has a weight of 25 kilograms, then 250*25= 6250 calories (or 62.5 kilocalories) needed per day to maintain the weight.
