Inside the top left box 1 is written, inside the top right box 2 is written, inside the bottom left box 3 is written, inside the bottom right box 4 is written.

Which of the following shows the correct match of the box numbers and the genotype of the offspring?

1 = Tt; 2 = tt; 3 = Tt; 4 = tt
1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt
1 = Tt; 2 = Tt; 3 = tt; 4 = tt
1 = Tt; 2 = tt; 3 = tt; 4 = tt

Explanation:

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Answer:

Structural classification of neurons

Explanation:

Structural classification of neurons is based upon the number of processes that extend out from the cell body. Three major groups arise from this classification: multipolar, bipolar, and unipolar neurons. Multipolar neurons are defined as having three or more processes that extend out from the cell body

How are animals similar? All animals are made of many cells. Most animals can move on their own. Like all living things, animals grow, change, reproduce, and respond to their environment.

Animals are made up of several cells. Most animals have independent movement. Animals develop, transform, reproduce, and react to their surroundings like all other living creatures do.

Any eukaryotic multicellular organism of the biological kingdom Animalia is referred to as an animal.

The majority of creatures in this kingdom lack a cell wall, are heterotrophic, motile, have specialised sensory organs, and originate from blastulae during embryonic development.

According to some, the fundamental distinctions between humans and other animal species are our capacity for complex reasoning, our use of complex language.

Also, the capacity for problem-solving, and the capacity for introspection (this means describing your own thoughts and feelings).

Multiple cells make up an animal. The majority of animals can move on their own. Like all other living things, animals grow, change, reproduce, and respond to their surroundings.

Thus, this way, many animals contrasts each other.

If there is a change in a squid's messenger RNA, this change does not appear in its genetic material. This change neither will be inherited by its offspring.

During gene transcription, a fragment of DNA called gene is used as template to generate a messenger RNA (mRNA).

Subsequently, this mRNA is used as a template to create a protein by a process known as translation.

The mRNA is a molecule that carries the genetic material from DNA to protein but this process does not modify the genetic material.

The diagram is not found here, but the order of steps in the cellular division is interphase (G1, S and G2) >> mitosis >> cytokinesis. It is the cell cycle.

The cell cycle refers to the events that occur from a cell form until it divides to produce two daughter cells.

The cell cycle can be divided into interphase, mitosis and cytokinesis (i.e., division of the cell cytoplasm).

Interphase has there main steps, i.e.,  Growth 1 (G1) phase, Synthesis (S) phase, and Growth 2 (G2) phase.

In turn, mitosis can be divided into prophase, prometaphase, metaphase, anaphase and telophase.

Binomial nomenclature is important in the classification of organisms because it is recognized by scientists everywhere no matter where they're from.

“Binomial nomenclature is the biological system of naming the organisms in which the name is organised of two words, where, the first word indicates the genus and the second term indicates the species of the organism.

Thus, it is recognized by scientists everywhere no matter where they're from

Answer:

hi there, proteins are related to DNA  because DNA carries the instruction for synthesizing  proteins, which can code for a certain amino acids based on the sequence.

Explanation:

A change in  base sequence can be either good or bad. But... Usually... a mutation could be a main factor that changes the sequence of the protein, which causes it to code for a different amino acid than the original. Base pairs could either substituted,  deleted, or inserted, which usually are what a mutation could be caused by or consisted of. This is also known as a gene mutation, which are changes in genes .

Animal behaviorists have found that animals gain from developing bonds with trustworthy humans, but doing so calls for a lot of motivation and understanding about the animal's behavior.

The scientific study of non-human animal behavior is called ethology, and it often focuses on behavior in natural settings and sees behavior as an evolutionary adaptive quality.

Animal behavior is an animal's response to stimuli, and there are both acquired and intrinsic types of animal behavior.

Dogs who have been trained to obey commands are an example of animal behavior. In contrast, inherent behavior includes mating cues like bird crowing and peacock dancing before a storm.

Animals benefit from forming relationships with dependable humans, according to animal behaviorists, although doing so requires a lot of drive and knowledge of the animal's behavior.

Anyone lacking sufficient motivation or missing the necessary knowledge could suffer considerable harm if they attempted to interact with the animal.

Thus, it is important to design field studies that will not make wild animals associate humans with food.

Pea plants can have yellow seeds as the meaning of y is correct if the allele combination yy is for yellow seeds are yellow and dominant.

This question involves a seed color gene, which has two alleles Y and y. Y, which represents the dominant allele codes for the YELLOW trait while y which represents the recessive allele codes for the GREEN trait. Therefore, a plant with Yy will have YELLOW SEEDS because the dominant Y allele is present.

Gregor Mendel has stated that a gene comes with two alleles. According to his law of dominance, one of the alleles called the DOMINANT allele is capable of masking the phenotypic expression of another allele called the RECESSIVE allele.

Thus it is clear that yellow and dominant are the meaning of y is correct if the allele combination yy is for yellow seeds.

I expect that this might help you out.

Explanation: The process of Photosynthesis is simple.

The three events that take place in "Photosynthesis", are:

1. Absorption of light energy by chlorophyll.

2. Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.

3. Reduction of carbon dioxide to carbohydrates.

Answer:

D

Explanation:

The amount of Carbon dioxide (CO₂) that is trapped in the atmosphere is released by the burning of the fossil fuels and from the industrial pollution. In addition to this, some amount of it also released by the animals and human beings. This stored CO₂ in the atmosphere is then transported to the oceans with the help of rainfall. When this CO₂ reacts with water it forms  weaker acid, which is commonly known as the Carbonic acid. Due to this, the pH level of ocean water decreases. As a result of this, it affects the ocean water chemistry and the marine life. Due to this ocean acidification, the marine species namely the corals and various types of planktons are not able to form the hard parts like the shell and skeletal parts. This carbonate water dissolves the existing shells and erodes the particles away. The increase in the carbon content in the atmosphere will also lead to precipitation that will wash away the rock particles and other sediments, that are present in the coastal areas. In addition to this, the plants also will be affected due to this carbon containing water.
