Answer:
1) The fossils are from a descendant of animal T.
2) Organisms with traits that help them survive and reproduce in their environment pass on those traits.
3) A, C, B
4) Which animal is older?
5) Fossils of Archaeopteryx have traits of both dinosaurs and birds.
Explanation:
The fossil records are used to show that modern creatures are distinct from those from the past and to illustrate how evolution has progressed, hence for questions 1- B, 2- B, 3- D, for 4- D.
What is the fossil record?Due to individual variation within a population, certain members of the population are more likely to live and procreate under a specific set of environmental conditions.
The majority of these people live longer and have more children, passing on their beneficial features to the following generation.
C has the most similar structure, B has the second most similar structure, and A has the least similar structure.
Two separate creatures' petrified bones have been found by scientists. To discover more about fossils, the experts consult the fossil record.
Therefore, modern creatures are distinct from those from the past, and to illustrate how evolution has progressed, hence questions 1- B, 2- B, 3- D, for 4- D.

what are the chances that a color blind man will have a color blind grandson what are the genotypes for all involved.
Answer:
Depends
Explanation:
It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.
which of the following is an indicator of good water quality?
high levels of nitrates
high levels of phosphates
zero turbidity
all of the above
Answer:
all of above
Explanation:
all of the above
Answer:
Zero Turbidity
Explanation:
High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too
The first unstable compound formed during C3 cycle is:
(a) 3-carboxy,2-keto, 1,6 bi phosphorobitol
(c) 2-carboxy,3-keto,1,5 biphosphorobitol
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
(d) 3-carboxy,3-keto, 1,6-biphosphorobitol
Answer:
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
Explanation:
2-carboxy, 3-keto, 1,5-biphosphorobitol is the first unstable molecule formed during the C3 cycle. Due to its instability, this molecule is quickly broken down into two molecules each containing 3 carbon atoms, called 3-phosphoglyceric acid, this breakdown is done through water in a process known as hydrolysis.

Parent cross: rough, soft peas X smooth, hard peas F1: all rough, hard Test
cross: rough, hard X smooth, soft peas F2: 115 rough soft, 110 smooth hard, 8
rough hard, 12 smooth soft
Identify which traits are dominant, and either support or refute the hypothesis
that the traits rough/smooth and soft/hard assort independently according to
Mendel's law,
Answer:
rough (RR or Rr) and hard (HH or Hh), are the dominant traits. smooth (rr) and soft (hh), are the recessive traitsWe reject the hypothesis because genes are linked, so they do not assort independently.

How does the long-term overuse of antibiotics lead to pathogen resistance???
hope this helps you
have a nice day:)
Anytime antibiotics are used, they can contribute to antibiotic resistance. This is because increases in antibiotic resistance are driven by a combination of germs exposed to antibiotics, and the spread of those germs and their mechanisms of resistance.

functional group of Acetaldehyde
Answer:
―CHO
Explanation:
Organic compounds are compounds that contain carbon-hydrogen bonding in their structural formula, hence, virtually all organic compounds are referred to as HYDROCARBONS. Organic compounds consists of a wide variety of groups, which are individually identified by their FUNCTIONAL GROUP.
The functional group of an organic compound is responsible for its chemical behavior irrespective of other atoms in its structure. According to this question, ALDEHYDE GROUP is an organic compound also called ALKANAL. It has the functional group as follows:
R - C - H - O
Where R is a side chain
- The second member of the aldehyde group is called ACETALDEHYDE with the chemical formula; CH3CHO. Since it is a member of the aldehyde group, its functional group is -CHO.

Describe Darwin's theory of evolution.
I need answers only in points for my lil sis, otherwise i'll report it..I'll reward brainliest to correct answer.
Answer:
Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. Individuals that are poorly adapted to their environment are less likely to survive and reproduce.The crossing of a buffalo and a cow to produce a beefalo is an example of -

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

Part D A scientist comes up with an idea to reintroduce a shark that eats lionfish into the Atlantic Ocean. What are the possible benefits and risks of this idea? In your answer, state two questions you’d ask the scientist before agreeing to the plan.
Answer:
The shark may balance out the lionfish population. However, its presence in the ocean may also negatively affect other organisms. The shark may start preying on natural species, leaving little food for native predators. Two questions to ask the scientist are, Does this shark have any natural predators in the Atlantic Ocean to help control its population numbers? and What other organisms does the shark eat?
Explanation:
i got this from edmentum-
Although some species of grouper and shark may be able to eat them, lionfish have relatively few predators in the area they have invaded because of their deadly spines. Although lionfish are widely distributed, most sharks won't readily eat them.
What eats lionfish into the Atlantic Ocean?The shark might maintain lionfish populations in balance. Its presence in the ocean, however, might also have a harmful impact on other organisms. It's possible that the shark will start eating native animals, leaving little food for them.
Do this shark's natural predators in the Atlantic Ocean aid to regulate its population numbers? Are two queries to put to the expert. What other kinds of creatures does the shark consume?
Therefore, Because the Moray was discovered in a location where divers would not have been searching, this is the first confirmed instance of natural predation of the invasive lionfish in the Atlantic Ocean.
