I will give you brainlest if you can answer right color blindness (due to a mutation on the x chromosome,a person can't see certain colors (positive or negative or neutral
Answer:
i would say negitive
Explanation: its a bad effect on life.
Answer:
Negative
Explanation:
The mutation that causes color blindness is negative for many reasons. First off, not being able to see color can cause you to not be able to do certain things in life. For example driving, if you can't see the correct colors to know when to stop or go, you can't safely drive. There are also some jobs where colors are important. Such as jobs that have to do with fixing colored wire. It's also bad because of how it takes away one of our senses and holds us back from seeing things and completeness. People who are colorblind can not truly experience the world like a person who can see color can.
How the oxygen levels have an effect on rivers and streams?
Answer:
All terrestrial and aquatic animals need oxygen to survive. Many aquatic macroinvertebrate species depend on oxygen-rich water. Without sufficient oxygen they may disappear. Even a small change in dissolved oxygen concentration can affect the composition of aquatic communities. Many fish require a certain dissolved oxygen range in order to survive
Aquatic life- animals living in water use up dissolved oxygen. Bacteria take up oxygen as they decompose materials. Dissolved oxygen levels drop in a water body that contains a lot of dead, decomposing material.
Elevation- the amount of oxygen in elevation increases. Since streams get much of their oxygen from the atmosphere, streams at higher elevations will generally have less oxygen.
Salinity (saltiness)- Salty water holds less oxygen than fresh water.
Temperature- cold water holds more dissolved oxygen than warm water.
Turbulence- more turbulence creates more opportunities for oxygen to enter streams.
Vegetation- riparian vegetation directly affects dissolved oxygen by releasing oxygen into the water during photosynthesis. It indirectly affects dissolved oxygen concentrations because vegetation shading a stream may decrease water temperatures, and as temperature decreases dissolved, oxygen increases.

biotechnology deals with
Answer:
Explanation:
Biotechnology is technology that utilizes biological systems, living organisms or parts of this to develop or create different products. Brewing and baking bread are examples of processes that fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).
Answer:
Biotechnology is the use of biological systems found in organisms or the use of the living organisms themselves to make technological advances and adapt those technologies to various fields. These include applications in multiple fields, from agricultural practice to the medical sector. It does not only include applications in fields that involve the living but also any other field where the information obtained from the biological aspect of an organism can be applied.
Biotechnology is particularly vital when it comes to the development of minuscule and chemical tools, as many of the tools biotechnology uses exist at the cellular level.

Answer:
This question is incomplete but the completed question is below
The Nature Conservancy is an organization that protects a variety of habitats around the world. A project this organization would probably support is one that
(1) uses endangered animals for medical research
(2) protects the biodiversity of areas for future generations
(3) alters habitats for industry and housing
(4) prevents animal species from migrating to other habitats
The correct answer is (2)
Explanation:
Protecting habitats (which is the main "support" of this organization) will have to do with ensuring organisms live and are comfortable in the natural habitat they are found without or protected from "transgression" by humans and other possible biotic and even abiotic factors. Since, different organisms will normally live together in a community in order to "satisfy" the food chain and survive, this organization will most likely support projects involving the protection of biodiversity in different areas of communities of organisms for these organisms' future generations.

Explain how osmosis will affect animal cells when the cells are placed into and environment with a low water potential compared to the intracellular water potential
Answer:
Explanation:
The cytoplasm in animal cells is surrounded by a membrane, which delimits the cell and its surroundings. As opposite from the plant cells, animal cells do not have a cell wall.
Osmosis is the process in which a solvent diffuses across a semipermeable membrane (like the cell membrane) from the zone with the lower concentration of solutes to the zone with the higher concentration. That means that water, in this case, will diffuse spontaneously across the cell membrane from the place with more water molecules (usually, the exterior of the cell) to the place which has less water molecules, or is more concentrated (in this case, the cytoplasm). This diffusion will continue until an equilibrium is reached.
If we place an animal cell, which does not have a cell wall, into an environment with a low water potential, the water will flow from the exterior to the interior. If the water potential is very low compared to the one of the cytoplasm, the cell can receive too much water and explode. This process is called cytolysis.
The membrane surrounds the cytoplasm of animal cells, defining the cell and its surroundings. Animal cells do not even have a cell wall, in contrast to plant cells.
Osmosis is a process by which a liquid diffuses all over a semipermeable membrane from the zone with the lowest solute concentration to a zone with the highest concentration. In this scenario, water diffuses spontaneously across the cell membrane from a location with more molecules of water to a location with fewer molecules of water or a greater density of molecules of water. This diffusion will continue until an equilibrium state is reached.When we place an animal cell with no cell wall in an environment with a low water potential, fluid will move from outside to inside. If the cell's water concentration is particularly low in comparison to a cytoplasm's, the cell may receive too much water and explode. It is known as cytolysis.Learn more:brainly.com/question/24914954

Which is a description of the Paleozoic era?
A. The rise of life
B. The age of the dinosaurs
C. The hottest era
D. The era of humans
Answer:
The rise of life
Explanation:
A.P.E.X.
A description of the Paleozoic era is A. The rise of life.
What is the Paleozoic era?The Paleozoic Era was a geological era that spanned from about 541 to 252 million years ago. It is often referred to as the "Age of Invertebrates" because it was during this time that the first major diversification of animal life occurred, and most of the animal life was invertebrates.
This era also saw the emergence of fish, amphibians, reptiles, and the first land plants. The Paleozoic Era ended with the largest mass extinction in Earth's history, known as the Permian-Triassic extinction event, which wiped out about 96% of marine species and 70% of terrestrial species.
The Paleozoic Era is a geologic era that began about 541 million years ago and lasted until about 252 million years ago. During this era, there were several major events that shaped the Earth's history and led to the evolution of new life forms:
During the early part of the Paleozoic Era, there was a sudden burst of new life forms, including many of the major groups of animals that we know today. This is known as the Cambrian explosion.
Therefore, A) Paleozoic era, is the correct answer.

Tachar lo que no corresponda: a) la respiración celular es el proceso que llevan a cabo las células de LOS ANIMALES / TODOS LOS SERES VIVOS para INCORPORAR LA ENERGÍA LUMÍNICA / LIBERAR LA ENERGÍA QUÍMICA contenida en la glucosa
Answer:
a) la respiración celular es el proceso que llevan a cabo las células de TODOS LOS SERES VIVOS para LIBERAR LA ENERGÍA QUÍMICA contenida en la glucosa.
Lo que no corresponde es: "los animales" e "incorporar la energía lumínica"
Explanation:
La respiración celular es uno de los procesos más importantes para la vida, y no es propia sólo de los animales, sino de todos los seres vivos. La misma puede ser aeróbica o anaeróbica, dependiendo de la presencia del oxígeno.
Durante la respiración celular, se libera energía química contenida en la glucosa, no se incorpora energía lumínica. Lo que sucede es que es una reacción exogénica, lo que significa que se libera energía, que luego será ATP y servirá para otros procesos.

PROJECT: RESEARCH AND LEARN: PLANT REPRODUCTION Project Overview For this assignment, you will need to select two specific plants. One must reproduce sexually and the other asexually. Instructions You will describe the plant and the specifics of how they reproduce. Your description must include a step-by-step explanation. Your paper should be approximately 250 words in length.
Answer:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.
