Biology books used to describe interphase as the “resting phase.” Based on what we know now, what was wrong with this term?

Answers

Answer: because in the interphase the cell still goes through changes(growth, replication of its DNA), they are just not visible by microscope. Therefore, the cell isn't resting.

Answers

It would be D. Fossils fuels.
People born remains of those organisms to form fossil fuels for energy.

Answer: It's C

Explanation: Plankton have been in the sea for along time, and oil takea millions of years to recover. So when a dead plankton dies and drops to the ocean floor, the energy in the oil basically comes from sunlight that the plankton trapps with a chemical inside of it which produces oil.

Make a prediction of this: A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate. After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they measured the amount of melted water on each plate. Their results showed that the plate treated with beet extract contained more liquid water than the plate treated with salt.

Answers

Answer:

extract of beet roots could be used as antifreeze for water systems

Explanation:

In science, a prediction can be defined as a plausible conjecture that is subsequently proved (or rejected) using the scientific method. In other words, a prediction is the expected result obtained if the hypothesis is true. Scientists make predictions based on falsifiable hypotheses which can be tested through experimental and/or observational procedures. In this case, it could be predicted that the extract of beet roots could be used as anti-freeze for water systems in cold climates.

What is dna replication?

Answers

Answer:

In DNA replication, cell machinery copies strands of DNA.

Explanation

DNAs, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides. These contain genetic information essential for growth, reproduction, and cell repair.

Nucleotide monomers are made up of, a 5-Carbon deoxyribose sugar,  one nitrogenous base (adenine, guanine thymine, and cytosine)  and a phosphate group.

Nucleotides, deriving their name from their nitrogenous bases, pair up to form base pairs. In base-pair formation, Adenine and Thymine form double bonds, while cytosine forms triple bonds with guanine...

DNA polymerase facilitates either DNA synthesis, by adding free nucleases to parent strands -these are first unwound and separated by helicases DNApolys synthesize DNA in 5'-3' direction; due to its restricted movement, there are only two modes of replication: continuous from the point of strand separation, the fork, and discontinuous from the fork.  In continuous replication, DNApolymerase moves uninterrupted along the 3'-5 oriented template, adding nucleotides to the free hydroxyl group at its 3' end to produce the 5'-3' oriented leading strand. During the synthesis of the 3'-5' oriented lagging strand, DNApolymerase  moves backwards along the template from the replication fork; DNA helicase separates the strands, and DNApoly's addition of nucleotides is periodically interrupted while  forming discontinuous Okazaki fragments. Ligase enzymes assemble nucleotide strands of RNA and DNA -here, DNAligase assembles these fragments into continuous strands, producing two identical new helixes formed from a parent and newly replicated strand respectively.

Answers

Answer:

The correct words that film in the blanks are;

Polarity

Cohesion

Hydrogen bonds

Heat

Ice

Solvent

Solutes

Explanation:

Water is a highly polar molecule. Its polarity allows it to form strong intermolecular hydrogen bonds which accounts for the forces of cohesion in the water.

The hydrogen bonds form and break with evolution of heat hence accounting for the role of water in temperature regulation.

Ice is less dense than water due to spaces in the solid. Water is regarded as a universal solvent for polar solutes. Blood and other aqueous body clouds usually contains many dissolved solutes.

Adaptations that help an organism survive appear quickly. True or False? And why

Answers

Answer:

false

Explanation:

is not worth it to do that

According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.

What condition that make organism adaptive?

Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.

This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.

If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.

Therefore, it is false that, Adaptations that help an organism survive appear quickly.

Trilobites appeared approximately 521 years ago and disappeared approximately 250 million years ago. During which era did the trilobites live?

a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These

Answers

Answer:

C. Paleozoic

Explanation:

Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.

We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.
