What is unique about the
protein channels which allow molecules to travel by facilitated diffusion?
A. Each channel only allows one type of molecule to pass through it
B. The channel modify the molecules DNA as they pass-through
C. The channels move molecules very quickly
Please help!!!! 10 points
Answer:
A. Each channel only allows one type of molecule to pass through it
Explanation:
Transmembrane proteins from channels spanning the membrane that create hydrophilic tunnels. They only enable diffusion across the protein channel into the cell, for their target molecules.
These are highly specific-they only allow one type or group of related molecules to use the channel. These are types of transmembrane channels, embedded within the membrane, help to maintain selective permeability, while simple diffusion of other small, uncharged molecules can readily occur.
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.

Why is uranium lead dating better than radiocarbon dating?
Answer:
Uranium-238 has a much longer half-life of 4.5 billion years versus Carbon-14's 5,730 years.
Explanation:
Radioactive Carbon-14 or [tex]^{14}C[/tex] is typically formed in the upper atmosphere. In plants, it gets incorporated into organic molecules through photosynthesis, and this material is ingested by consumers.
It is used for the process of radiocarbon dating of fossils and formations. Radioactive isotope dating is an effective means of identification due to the unstable nature of the isotope used and the predictable rate of decay.
Over time they decay to give off an electron, in an effort to become a more stable element. For instance, [tex]^{14}C[/tex] has a relatively short half-life and half the in a sample becomes Nitrogen over a few thousand years (5,730 years).
However, for older samples, other isotopes are used because their long half-life may range between a million to billions of years. Uranium-238, with a half-life of 4.5 billion years is often used in geochronology; uranium-lead dating is suitable for older specimens.

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.

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.

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.

what are the three primary methods scientists use to group organisms into monophyletic clades? please provide examples for each. which has caused the major reorganization of phylogenies, i.e. the fall of the kingdoms, and why only recently?
Answer:Cladistics (/kləˈdɪstɪks/, from Greek κλάδος, kládos, "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.
Explanation: Modern taxonomists seek to employ classification schemes that are consistent with the underlying evolutionary relationships among species. As shown below, phylogenetic analyses present a way to test existing Linnaean classifications (some of which predate widespread acceptance of the fact of evolution) and to determine which classifications are consistent with evolutionary history, and which require modification.
