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

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.

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.

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.
Which of the following would give a person the most energy?
a starch
a monosaccharide
a disaccharide
glucose
Answer:
I THINK IS D
Explanation:
The following that would give a person the most energy is glucose. The correct option is D.
What is glucose?Glucose is a monosaccharide ad it is the primary source of energy in plants and animals. The cells produce energy by converting food into glucose molecules.
Its structure is simple. It is a simple carbohydrate. The formula is C6H12O6. It is made up of carbon, hydrogen, and oxygen. It is the only form and basic form of energy.
Every plant and animal produce glucose by body function, and if there is excess glucose in the body, the body saves it in the form of glycogen in the adipose tissues.
In all others, starch does not produce energy. It gives structural strength to the body, and disaccharides are a unit, but not all disaccharides provide energy to the body.
Thus, the correct option is D. glucose.

Is the Monocercomonoide considered a life form?
Answer:
Monocercomonoides isn’t a living fossil, a holdout from the days of the earliest eukaryotes, Karnkowska notes. Its closest relatives still have small mitochondria, suggesting that it jettisoned the organelles fairly recently in evolutionary terms. She and her colleagues speculate that more eukaryotes missing mitochondria await discovery.

where are the choices?
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.

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.
