Explanation:
Sea floor spreading happens in which plate boundaries?
Answer:
Divergent plate boundaries.
Explanation:
"As upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre".

Which statement is NOT a part of the cell theory?
Cells come from preexisting cells.
Cells are the basic unit of function of living things.
Cells are the basic unit of structure of living things.
Cell parts such as chloroplasts are self-replicating.
Answer:
Cells such as chloroplasts are self replicating
Explanation:
a chloroplast is not a cell its an organelle.
Cell Theory is a scientific theory proposed by Schwann in the year 1839. The cell theory has primary three postulates, which are used to describe the functioning of cells.
The correct answer is:
Option D. Cell parts such as chloroplasts are self-replicating.
The postulates of the cell theory are:
1. The cell theory states that all living cells arise from pre-existing cells.
2. The cells are the basic structural and functional unit of life.
3. The hereditary information is passed on from cell to cell, and the energy flows within the cell.
Thus, the statement that is not a part of cell theory is that chloroplast are self-replicating.

How do you think the body processes monosaccharides differently than polysaccharides? Would they take the same amount of time to digest and harvest energy?
Answer:
Polysaccharides from cell walls make up the fiber humans eat, while monosaccharides provide the sweetness in foods. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream.

Sally conducts an experiment measuring plant growth. She finds that after two weeks, a plant that receives water grew 4 cm, but the plant that received soda died. What is the term for what is being measured?
Answer:
The correct answer is - the dependent variable.
Explanation:
In any study or research, the variable is that measured or affected by the change occurs lace in an experiment is called the dependent variable. The dependent variable depends on the factors or the variables that are changed in the experiment.
In this particular study, the variable which is measure is the height or growth of the plant which depends on the change in the hydrating supply so the dependent variable will be - the growth of the plant.

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.
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.
Scientists theorize that oil and natural gas formed from the remains of microscopic manne organisms called
A) mussels
B) seashells

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
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.

what molecules form proteins when linked together with covalent bonds
Answer: Amino Acids
Explanation:
Proteins are formed when the organic Amino acids are linked together with covalent bonds. This means that proteins can be broken down into amino acids which is what the bond does when it processes proteins.
Amino acids are principally made up of Carbon, Hydrogen, Oxygen and Nitrogen and are classified into three groups namely: Essential amino acids , Nonessential amino acids and Conditional amino acids.
ln certain species of plant, one purebred
variety has hairy leaves and another pure-
bred variety has smooth leaves. A cross of
the two varieties produces offspring that all
have smooth leaves. Predict the ratio of
phenotypes in the F2, generation.
Answer:
If crossing plants with hairy leaves and smooth leaves produces plants with smooth leaves in F1, the phenotypic ratio of plants with smooth leaves:hairy leaves in F2 will be 3:1.
Explanation:
It is assumed that, if the first descendants of this cross presented smooth leaves, this represents the dominant characteristic.
If in the crossing of two plants, the parental generation consists of two pure plants for the characteristic aspect of the leaf, one with hairy leaves (s) and another with smooth leaves (S), the first filial generation (F1) will be of hybrid plants with a phenotype of smooth leaves (Ss), which represents the dominant characteristic.
Parental Generation:
Smooth leaves SSHairy leaves ssPunnett Square F1
Alleles S S
s Ss Ss
s Ss Ss
F1 : 100% plants with smooth leaves Ss
The second filial generation (F2) results from the crossing of F1 individuals, so:
Punnett Square F2
Alleles S s
S SS Ss
s Ss ss
The result of the offspring in F2 is:
Genotype
Pure smooth leaves SS 25%Smooth hybrid leaves Ss (heterozygous) : 50%Pure hairy leaves ss: 25%Genotipic ratio: pure smooth leaves:hybrid:pure hairy leaves 1:3:1
Phenotype
Smooth leaves SS + Ss: 75%Hairy leaves ss: 25%So the phenotypic ratio of smooth leaves: hairy leaves will be 3:1.

A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota.
Any organism which has a closed membrane for a nucleas is a eukaryotic cell.

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