what are the effects of sunlight on the aquatic life inhabiting amazon river
Answer:
the effects of sunlight on the aquatic life inhabiting the Amazon River. The center of all aquatic life in the Amazon is located in The Amazon Basin, the sun makes sure that all fish and plant life can sustain life.
The sunlight affects the aquatic species that lives in the Amazon River. The Amazon Basin is the epicenter of all aquatic life in the Amazon, where the sun ensures that all fish and plant life may survive.
What is Amazon Basin?The region of South America that the Amazon River and its tributaries drain is known as the Amazon basin. Approximately 6,300,000 km2, or 35.5 percent of South America, is covered by the Amazon river basin.
The Amazon basin not only contains the world's largest remaining tropical rainforest, it also harbours at least 10% of the known biodiversity, including endemic and threatened species of plants and animals, and its river contributes 15–16% of all river flow into the oceans.
The aquatic animals that inhabit the Amazon River are impacted by sunlight. All aquatic life in the Amazon is concentrated in the Amazon Basin, where the sun ensures the survival of all fish and plant life.
Thus, this is the chief effect of sunlight on the aquatic life inhabiting amazon river.

A bird that can easily out complete other birds for its food and that can produce many eggs has high what?
Answer:
Fitness or aptitude
Explanation:
Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.

What happens when we know about other living beings ?
Please I need it soon
Answer:
In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.
Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

When heat is introduced to matter, what happens to the matter at the molecular level?
Explain in science
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

How do T-cells help with destroying viruses?
Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.

Explanation:
The process of the natural selection produce change occurs when there is the individual member of species.
What is species and natural selection?It refer to the group of the organism where it should be reproduced in a natural way with one another and also developed the fertilization off-spring.
The organism that does reproduction at a se-xually only, the species population, and the animal species should not change the natural selection.

1.What is budding
2.What is vegetative propagation
[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]
Budding - It is a type of asexual reproduction where in a daughter organism is formed from a small projection known as bud. it develops as an outgrowth due to the repeated cell division on the parent body. when fully grown it detects to grow into a new independent individual
For.eg. hydra
Vegetative Propagation - it is a type of axle plant reproduction in which new plans are obtained from a part of the parent plant. under favorable conditions various touch to take part in the type of reproduction.this is known as natural vegetative propagation where plants parts like root stem and leaves develop into new plants
the property of vegetative propagation is used in cutting tearing and grafting these are known as the method of artificial vegetative propagation. they are used for many plants like sugarcane , rose, etc

Members of different species do not produce offspring due to:
A) Behavioral Speciation (differing mating rituals)
B) Temporal Speciation (varying breeding times)
C) Mechanical Speciation (gamete incompatibility)
D) any of these
(Please Answer Fast)
Answer:
Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation. These barriers can be split into two categories based on when they act: prezygotic and postzygotic.
Explanation:
So the answer would most likely be C.

How does the position of Earth and its orbit affect climate change?
Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.
Complete the passage about the process of subduction.

The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes. a) oceanic crust at convergent boundary b) heats up.
What are convergent boundaries?Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.
In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices. The Himalayas and Los Andes are examples of these collisions.
Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.
When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.
The subduction of oceanic crust at convergent boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water heats up the mantle and allows for the creation of magma.

What is the most likely reason that horses and mountain goats have hooves?
They have homologous structures because they have a common ancestor.
They have analogous structures because they have a common ancestor.
These are vestigial structures in both animals because they are not used.
These are similar structures due genetic mutations.
What is the answer to this?
Answer:
They have homologous structures because they have a common ancestor.
homologous structures because they have a common ancestor is the most likely reason that horses and mountain goats have hooves.
what is homologous structure ?Homologous structures shoe the same structure, but may have a distinct function, it indicate a common ancestor.
A homologous structure is an organ or bone seen common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor.
on the other hand analogous structures where two unrelated species have structures with similar forms or functions due to convergent evolution.
