Problem 1
In dust bunnies, short ears are dominant to long ears. If a heterozygous female mates
with a long ear male, what are the chances their offspring will have short ears?

Answers

Answer:

50% or 1/2

Explanation:

This question involves a single gene coding for ear length in dust bunnies. The allele for short ears (S) are dominant to the allele for long ears (s). This means an heterozygous individual (Ss) will possess short ears.

According to this question, If a heterozygous female (Ss) mates with a long ear male (ss), the parents will produce gametes as follows:

Ss - S and s

ss - s and s

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Ss, Ss, ss, ss

- Ss (1/2 or 50%) offsprings will have short ears.

- ss (1/2 or 50%) offsprings will have long ears.

The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Explanation:

Can I have brainliest?

Answer:

Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.

Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

Why would a normally aquatic or marine species adapt to the supralittoral fringe where they have to deal with desiccation and temperature stress?​

Answers

Answer:

In order to survive.

Explanation:

A normally aquatic species adapt to the supralittoral fringe in order to survive in that environment. Supralittoral zone also referred to the area on coastlines and estuaries, that is regularly splashed, but not submerged by ocean water. This environment is different for the marine organisms that causes adverse effect on the marine organisms but these marine animals has the ability to adapt that environment by using certain mechanism in order to survive and easily reproduce in that environment.

Which of the labeled structures is an adaptation that is primarily responsible for helping a paramecium control its water balance?
Paramecium diagram
A. Structure A
B. Structure B
C. Structure C
D. Structure D

Answers

Structure D , The term "contractile vacuole" refers to this structure. The vacuole gathers extra water from the cytoplasm and contracts to release it. As a result, paramecium doesn't swell and explode in hypotonic liquids.

Why are contractile vacuoles necessary for organisms?

Specialized contractile vacuoles control the amount of water in cells. Its spherical form allows it to gather extra cell fluid and empty it outside. It is essential for preserving the osmotic pressure inside the cell. Protists are eukaryotes with only one cell and are found in wet and aqueous habitats.

The name "contractile vacuole" refers to what?

As its name implies, the contractile vacuole expels water from the cell by contracting. The contractile vacuole periodically expands (collecting water) and contracts (releasing water). Several seconds are required for one cycle, depending on the species .

Which of the following scenarios is an example of temporal isolation?


A.

Fossil evidence suggests that a number of members of one squirrel species evolved over time into two separate species, each on opposite sides of the Grand Canyon.


B.

Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.


C.

Two species of tree crickets live in a Costa Rican dry forest. Their habitats and ranges overlap. The two species never interbreed because the calls of the males are different and do not attract females of the other species.


D.

Indian paintbrush flowers vary greatly in color. Bumblebees form a search image for the most average common color and preferentially pollinate those flowers.

Answers

Answer:

B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.

Explanation:

Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.

Which of the following is not a function of tRNA

Answers

Answer:

connecting amino acid together to form proteins

hope it will help

Option D is correct. "connecting amino acid together to form a protein" is not a function of tRNA

Unlike DNA, there are three types of RNA that are involved in protein synthesis, messenger RNA, ribosomal RNA, and transfer RNA.

Ribosomal RNA (rRNA) and transfer RNA (tRNA) are not copies of the info in DNA, instead, their codes are created while in the DNA and then cut into smaller coded fragments.

Transfer RNA (tRNA) is found in cells' cytoplasm and ensures the correct amino acids are carried to mRNA codons to form polypeptide chains during protein synthesis. tRNA takes the amino acid to the correct location for protein synthesis in the ribosome.

Some of the functions of tRNA include:

Picking up amino acid specified by the codonTranscribing nitrogen bases into mRNA in the nucleus Recognizing appropriate codon in the mRNA

According to the explanation above, we can see that "connecting amino acids together to form a protein" is not a function of tRNA

A. Temperate forests have more biodiversity.
B. Temperate forests are more productive.
C. Temperate forests are closer to the equator.
D. Temperate forests have more seasonal changes.

Answers

Answer:

d

Explanation:

Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator. The tropical rainforest is a hot, moist biome where it rains all year long.

Tropical rain forests and temperate forests are different because temperate forests have more seasonal changes.

How are tropical rain forests different from temperate forests?

Tropical rainforests are found closer to the equator having less seasonal changes while on the other hand, temperate rainforests are found near the cooler regions having more seasonal changes.

So we can conclude that tropical rain forests and temperate forests are differen because temperate forests have more seasonal changes.

Why couldn't yeast use both sugar and artificial sweetener for cell respiration?

Answers

Yeast, sugar eating fungus, use oxygen to release the energy from sugar, much like humans, in the process called "respiration". The more sugar there is, the more active the yeast will be and the faster it will grow. Yeast feeds on sucrose, fructose, glucose, and maltose, which it converts to cellular energy through alcoholic fermentation.
Sugar is more suitable for respiration.
The artificial sweeteners are less effective at promoting yeast respiration than sucrose.

Yeast couldn't use both sugar and artificial sweetener for cell respiration because of the low calorie content of artificial sweetener.

What is artificial sweetener?Chemicals called artificial sweetening agents are used to sweeten food. They do not, however, provide our bodies with extra calories.Which one will have better yield?The sugars will have better yield because natural sugars like sucrose have more calories than artificial sugars.This increased energy will allow the yeast to metabolize faster and hence more carbon-dioxide is released.What is cellular respiration?

"Cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a compound called as adenosine triphosphate (ATP)."
