Some scientists have been concluded that the legs of modern land vertebrates evolved from the fins of ancient fish. What most likely provided the evidence for this conclusion?
- study the fossils of ancient land vertebrates
- Identity the numbers of ancient fish and ancient land vertebrates
- comparing the number of genes in modern fish to the number of genes in modern land vertebrates
- comparing the movements of genes in modern fish fins to the limbs of modern land vertebrates
Answer:
1- study the fossils of ancient land vertebrates
Explanation:
Some scientists concluded after performing a number of experiments that the legs of modern land vertebrates evolved from the fins of ancient fish. With the passage of time evolution occurs within the body of organisms. These changes occurs due to the surrounding environmental condition of that organism. When the organisms live in water, fins were present but when they go to the land so these fins change into legs. This type of evidence is provided by the scientist after studying the remains of ancient land vertebrates.

explain the life cycle of frog in detail
Answer:
The first stage is the egg stage. Eggs are usually laid in or near water. A frog can lay thousands of eggs at once. The eggs are laid in large groups. There are covered in jelly which makes them slippery. The jelly protects them from other animals eating the eggs.
The second stage is the tadpole stage. A tadpole hatches from the egg. The tadpole breathes using gills and moves like a fish. It uses its long tail to swim. Tadpoles eat tiny water plants.
The third stage is the froglet stage. It grows lungs and legs. Its gills disappear. Its tail gets shorter until it disappears too. The froglet swims to the top of the water to breath.
The last stage is the adult stage. A frog can leave the water now and live on land. It eats insects, worms and snails. Mother frogs return to the water to lay eggs. the air.

What’s the ecological niche of humans
Answer:
the context for the lived experience of humans and their communities, where they share 'kinship' and social and ecological histories
Explanation:
Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles, and Golgi apparatus.
Answer: The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
The explanation of how these organelles ensure that a cell has the proteins it needs below
The nucleus contains the genetic material of the cell: made up of one or more DNA molecules.
It governs all cellular functions and is also the place where ribosomes are produced, which have the important function of synthesizing or translating information for the production of proteins.
The rough endoplasmic reticulum is characterized by being formed by a series of channels, flattened sacs and cisterns, in these flattened sacs chains made of various peptides are introduced, with which complex proteins will be formed.
This structure's main function is to synthesize proteins, which are destined to different parts of the cell to develop multiple functions, in addition to controlling their structural and functional quality.
These same proteins travel to other parts of the cell, such as the Golgi apparatus.
Golgi apparatus is known as a cellular organelle whose function is to handle synthesized proteins.
The multitude of small vesicles are associated with the Golgi dictyosomes, grouped on the side adjacent to the ER and along the dilated rings of each cistern.
These Golgi vesicles are protein and lipid transport vesicles to and from the Golgi and between the Golgi cisterns.
Proteins, as they pass through the Golgi apparatus, undergo a modification process before being released.

Green plants are responsible for oxygen in
the atmosphere.
Green plants use photosynthesis, not cellular
respiration
Green plants are primary consumers.
DONE
Answer:
Green plants are responsible for oxygen in the atmosphere.
Explanation:
-Green plants undertake a process of photosynthesis, in which they use energy from the sun, carbon dioxide and water to form simple sugars and also release oxygen to the atmosphere. The simple sugars from the process may be used by the cells for energy or be stored in form of energy for future use.
-Oxygen is a product of photosynthesis which is released to the atmosphere.

2. Why does the sun and the moon appear to be the same size from Earth?
The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth
than the sun
The moon is bigger than the sun.
The sun changes size throughout Earth's orbit.
They are the same size.
Answer:
The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth
Explanation:
Although the the sun is roughly 400x wider than the moon, the moon is aproximately 400x closer to the Earth, and that is why seen from earth, sun and the moon appear to be the same size.
So answer is the sun is 400x wider than the moon, but the moon is also 400x closer to the Earth.
EXTRA:
There is a fenomenom called blood moon, when that happens, the moon appears to be bigger then normal (and it has a red glow about it).

Which hypothesis most likely explains the results at 60°C and 70°C? O A. The substrate has been used up because of the high temperature, O B. The enzyme has changed shape because of the high temperature. O C. The enzyme is only effective at very high temperatures, O D. The bonds in the substrate are weakened at high temperatures
Answer: Option B
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.

Specialization takes place when cells in your body produce a specific protein. for example, bone cells would produce proteins to support bones and stomach cells would produce proteins to support the function of the stomach. Why does this specialization occur?
A.The DNA in your bones contains recombinant DNA but not your stomach.
B. All of your DNA is in every cell (except red blood cells), it's just that different types of genes are activated in different cells.
C. Different cells contain only the gene for proteins that kind of cell needs.
D. Stomach cells do not produce DNA, but bone cells do.

What is Specialization?In order to become more effective, specialization in business entails concentrating on a single product or a small range of products. Specialization can boost productivity and give a company or economy a competitive advantage.
Macroeconomic specialization deals with the general advantage an economy holds in production, while microeconomic specialization deals with the specific actors and economic elements.
Specialization is an agreement within a community, organization, or larger group in which each of the members best suited for a specific activity assumes responsibility for its successful execution.

WHAT IS A DIHYBRID CROSS:A dihybrid cross is a cross between two individuals that are are heterozygous for two genes. In this question, a gene involving seed color and seed shape is used. The allele for round shape (R) and yellow seeds (Y) are dominant over wrinkled (r) and green seeds (y).A cross between two dihybrid i.e. RrYy × RrYy will result in the following offsprings:
