Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.

Choose an organism to use as an example.
Describe the organisms reproductive strategy:
discuss how this strategy is an adaptation for this organism:
Answer:
I will go with sponges :)
Sponges reproduce asexually. The parent begins budding, when the buds grow to a certain point, they break off and drift with the oceans current to a new place, settle down into the sand or rocks, and start the cycle all over again. Since sponges are stationary organisms (meaning that they cannot travel on their own.) They rely on the oceans current to spread their species across the oceans.
Answer:
I would do a Moon Jellyfish
Explanation:
Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower. The polyp essentially clones itself. The clone buds out of the original polyp and detaches to float freely in the water.

What 10 good ideas would you give to improve a zoo. Explain each with a sentence.
How are oxygen and carbon connected through the atmosphere, geosphere, and hydrosphere. Give an explanation of how a plant might use all three spheres
Answer:
Explanation:
To preserve Zoological garden expertise are needed to manage the creatures that are there.
Good and conducive environment should be provided for the animals.
Routine cleaning to avoid outback of diseases
Adequate resources should be provided this include food to avoid eviction of important species.
Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.
Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide
Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.
Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.
Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.

Indica que nivel de organización representa cada uno de los siguientes elementos ADN estómago neurona electrón átomo de oxígeno, agua, ser humano, músculo cardíaco, óvulo y sangre.
Answer:
Neuron- the level of organisation is cells.Because it s the functioning unit of nervous system.
The Blood's level of organisation is tissues because if is made of group of cells.
The stomach level of organisation is organ, because it is made up of group of cells and tissues to form part of the digestive system.
Heart muscles is made up of organs as it is the combination of tissues and cells therefore a muscular organ,
DNA -represents a molecular level,but because it is located in the cells , its represented this level.
Egg belongs to level of organisation which is cellular.
Oxygen atom level of organisation is.(cell)
water is a Compound.( tissues )since it is the combination of two atom cells( hydrogen and Oxygen)
Human being is organism.
electron level of organisations are the smallest particles.(cells)
Explanation:
why the relative numbers of mitochondria found in a muscle cell would be larger than the relative number found in a fat cell.
Answer:
The ATP is produced in the mitochondria using energy stored in food. ... Some cells have more mitochondria than others. Your fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.

Giving Brainliest to first correct and logical answer.
Explain why Calix having X chromosomes from his mother AND father meant chromosomal rearrangement was not the cause.
Answer:
Chromosomal rearrangment was not the cause because it wouldn't lead the mass of DNA per cell in Calix to appreciate by 40fg. It also wouldn't explain how he ended up with an additional sex chromosome altogether.
Explanation:
Chromosomal rearrangement occurs when one chromosome receives additional DNA while a different chromosome is missing DNA.

Each gene in a cell's DNA codes for a specific protein. True of False
Answer:
True
Explanation:
Answer:
true
Explanation:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Water hyacinths from Asia now grow in the United States and are crowding out animals and other plants.
Answer:
D.
Explanation:
Nonnative species is defined as the introduction of an alien species, foreign species or exotic species to a new region and affect the native species.

Introduction of non-native species can disturb the balance of an already-established ecosystem by the native species including plants and animals.
Hence, the correct option is D.
Answer:
D
Explanation:
Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is very important for many organisms. How is this different among ectotherms and endotherms?
Answer:
The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.
There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.
In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.
Explanation:
In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.
This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.
