Answer 2

Answer:

A. All are correct

Explanation:

Populations evolve, not individuals. ... A single organism is never typical of an entire population unless there is no variation within that population. Individual organisms do not evolve, they retain the same genes throughout their life.

Explain how temperature and amount of precipitation can affect the type of plants and animals found in the coniferous biome.

(150 WORDS OR A PARAGRAPH)

Answers

Answer:

Precipitation and temperature provide a suitable environment for the organisms and plants found in the coniferous biome. In this biome the temperature usually warm in summer that ranges from -40 degrees Celsius to 20 degrees Celsius over the year including warm summer and cold snowy winters. The rain or precipitation also affects biodiversity as the rainfall ranges from 30 to 89 cm over the year.

The high temperatures and rain make a warm, damp ecosystem that is suitable for organisms like insects and organism that depends on these insects and other organisms who requires these suitable warmer and climate in summer and cold winters also finds. The plants mostly have needles instead of leaves and coniferous that are able to found in these areas.

Why are recessive traits shown less than dominant traits?

Answers

Answer:

Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.

23. Each trait has two alleles. How many alleles would have to be a dominant allele for the offspring to express a dominant trait

Answers

Answer:

One (1) of the alleles

Explanation:

According to Gregor Mendel in his series of experiments, he discovered that two forms of a gene called ALLELE contributed to the formation of a trait. However, in his law of dominance, Mendel stated that one allele called the DOMINANT ALLELE has the ability to mask the phenotypic expression of the other allele called RECESSIVE ALLELE when present.

This means that, in a combination of both alleles in a gene (heterozygous), only one allele coding for a phenotypic characteristics will be expressed. This phenotype is called the DOMINANT TRAIT.

For example, if tall allele (T) is dominant over the short allele (t), the tall trait will be expressed when the genotype is "Tt" meaning that only one of the alleles would have to be a dominant allele for the offspring to express a dominant trait.

Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

Answers

Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...

Explanation:

Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.

Explanation:

Estuaries

-More than 80 percent of all fish and shellfish species use estuaries as primary habitat or as a spawning or nursery ground.

-Estuaries are often called the “nurseries of the sea”.

-Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea.

Abiotic factors

In an estuarine ecosystem, these factors are light, oxygen, water, nutrients, temperature, salinity, and space. So just divide these into three.

Biotic factors

These include plants and animals such as shrimp, fish, and oysters

Question 1:
C. Nervous

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate B because we aren’t using the integumentary system (skin, hair).
— We can eliminate D because the respiratory doesn’t instruct any systems, it just keeps them going.

Question 2:
D. Immune, Integumentary, Circulatory

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate C because we aren’t using the muscular system (muscles).
— We can eliminate B because we aren’t using the skeletal system (bones).

Question 3:
D. None of these

BECAUSE
— We can eliminate A and C because we need the integumentary system to maintain body temperature (the integumentary system uses skin to regulate body temperature).
— We can eliminate B because we need the muscular system to maintain body temperature (the muscular system uses its ability to contract muscles to create heat).

Question 4:
B. Digestive, Circulatory, Excretory

BECAUSE
— We can eliminate A and C because we need the excretory system to digest and maintain homeostasis (to prevent damage to the body).
— We can eliminate D because B is our answer.

Question 5:
B. Reproductive, Nervous, Endocrine, Circulatory

BECAUSE
— We can immediately eliminate A, C, and D because we need the excretory system (hormones) to reproduce.

In protein synthesis, the role of the ribosome is to: A. Translate mRNA into tRNA B. read the mRNA code C. Pick up and carry amino acids D. Translate tRNA into amino acids PLEASE HELP!

Answers

Answer:

B. read the mRNA code

Explanation:

Ribosomes are cellular organelles present in both eukaryotic and prokaryotic cells. The ribosome is the site of protein synthesis in a living cell i.e. it is where the translation of mRNA into protein (amino acids) occurs.

The mRNA molecule is read in the ribosome with the aid of another type of RNA molecule called tRNA (transfer RNA). The tRNA in the ribosome reads the mRNA codon using its anticodon and carries the corresponding amino acid to the growing polypeptide chain. Therefore, the ribosomes play the role of reading mRNA code during protein synthesis.

While the speed of the object may change at various times during a trip the average speed for the trip is found by dividing the total distance by the total time. The motion of the object can be changed by varying the amount of net force acting on the object or by varying the mass of the object.The teacher asked students to design investigations to determine how changing the forces acting on an object or the mass of the object would change its motion.
