How does the sperm come in contact with frog eggs?
The sperm is carried through a reproductive system
The sperm is placed on top of the eggs
The sperm is carried to eggs via water
Explanation:
the sperm is placed on top of the frog eggs
The sperm come in contact with the frog eggs as they are placed on top of the egg cells. Thus, the correct option is B.
What is fertilization in frogs?During the spring season or rainy season, frogs and toads move to ponds and slow flowing stream regions. When the male (sperm) and female (egg) come together in water medium, the female frog lays hundreds of eggs in the water. Frog’s eggs are not covered by a shell and it is comparatively very delicate in nature. A layer of the jelly holds the eggs together in place and provides protection to the egg cells. As the eggs are laid in the water, the male frog deposits sperms over them. Each sperm swims randomly in the water body with the help of the long tails. The sperms (male gamete) come in contact with the eggs (female gamete). This results in fertilization of the gametes.
The sperm come in contact with the frog eggs as the sperm is placed on top of the eggs.
Therefore, the correct option is B.

Answer:
A
Explanation:
From what I know this could be wrong, but in the four stages of natural selection, the first step is overproduction, the second step is adaptation, and the third step is competition or survival of the fittest. This means that only the organisms with the best adaptations for their surroundings will survive. COULD BE WRONG SORRY IF IT IS

What is free nitrogen? Nitrogen gas is called "free" nitrogen, meaning it is not combined with other kinds of atoms. Most organisms can use nitrogen only once it has been "fixed," or combined with other elements to form nitrogen-containing compounds.
Answer:
About 78% of the Earth's atmosphere is made up of "free" nitrogen (N2), produced by biological and chemical processes within the biosphere and not combined with other elements. ... One family of nitrogen compounds produced by nitrogen - fixing bacteria are called nitrates.
Explanation:
Hope this helps
Free nitrogen refers to nitrogen gas (N₂) that exists in the Earth's atmosphere as a diatomic molecule consisting of two nitrogen atoms bonded together. It is called "free" nitrogen because it is not chemically combined with other elements or atoms.
Nitrogen gas makes up approximately 78% of the Earth's atmosphere, making it the most abundant gas present. Despite its abundance, most organisms cannot directly utilize nitrogen gas in this form. This is because the bond between the two nitrogen atoms is very strong, requiring a significant amount of energy to break.
Therefore, free nitrogen refers to nitrogen gas (N₂) present in the atmosphere that is not chemically combined with other elements. It needs to undergo nitrogen fixation to be converted into usable forms before most organisms can utilize it.

They perform locomotion through crawling or creeping mode.They are mostly terrestrial animals. Their body is covered by dry and cornified skin. They do not possess external ear openings. Their heart is typically three-chambered, but exceptionally crocodiles have a four-chambered heart.Mammals are mammary glands in order to feed their young ones. Amphibians have the ability to live in both water and terrestrial habitats. They have two pairs of limbs. The Body is divisible into the head and trunk.
Birds are classified into the category of Aves. The presence of feathers is one of the most important characteristics of this type of classification.

How does the structure of DNA allow DNA to be copied without mistakes? Your answer
should include: hydrogen bonds, complementary strands, and semi-conservative replication
I will give brainliest to whoever answers best !! Pls
Answer:
DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together.
Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).The primary enzyme involved in this is DNA polymerase which joins nucleotides to synthesize the new complementary strand. DNA polymerase also proofreads each new DNA strand to make sure that there are no errors.
