Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation

Answers

Answer:

B. Overproduction

Explanation:

Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.

From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.

The farmer realizes he could sell mini-dragons as pets, but doesn't want them to breathe fire, because that would be dangerous. Suggest two parental genotypes for parents that would produce mini, non-fire breathing dragons.

Answers

Answer:

ddff  and DDFf

Explanation:

From the information given:

Let DD represents the dwarf traits and FF represents the ability for the dragons to breathe fire.

Also, if dd represents the normal traits and ff represents the inability of the dragons to breathe fire.

Then; we can cross a dominant trait for dwarfism which has a heterozygous trait for fire with a recessive trait of normal and nonfire.

The two parental gametes are: ddff  and DDFf

Using a Punnet Square:

         DF              Df

df      DdFf           Ddff

df      DdFf           Ddff

From above; we could observe that the proportion of progenitors that will be dwarf and at the same time unable to breathe fire is 50%.

fault generally occurs at a transform boundary. O A. normal OB. strike-slip O C. thrust O D. reverse ​

Answers

Answer: Read the question carefully

TRANSFORM BOUNDARIES: B. Strike-Slip

Explanation:

A reverse fault happens at convergent boundaries.

A normal fault happens at divergent boundaries

Hope this helps :)

The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.

What are transform boundary and strike-slip?

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.

"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.

Hence, option B is correct.

how do organisms with many cell types develop from a single cell

Answers

Answer:

Organisms develop from a single cell into many cell types, which are organized into tissues and organs. During development, cells use both inherited info and external signals from neighbors to “decide on” their behavior and identity.

Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.

What is cell division?

The process by which a parent cell divides into two daughter cells is known as cell division.

Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.

Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.

Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.

Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.

Thus, this way, organisms with many cell types develop from a single cell.

A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population

Answers

Answer: D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.

Explanation:

When an organism is able to reproduce asexually as opposed to sexually, it means that they do not require a mate to make offspring. Offspring of such organisms will therefore receive all their genes from one source.

Such organisms are able to reproduce very fast when they are presented with adequate conditions especially because they do not need another organism to do so. They will neither have to waste much energy nor have to go through the whole sexual process so they will be able to produce lots of offspring.

Animals are known to have offspring through asexual and/or sexual reproduction. The choices that has an argument for the advantages of asexual reproduction is that Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.

Asexual reproduction is simply known as a type of reproduction where offspring are genetically identical to the parent.

The offspring are regarded as clones that derives its root from the original parent.

A single individual can have offspring asexually and also in large numbers quickly.

The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features.

The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.

The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.

Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.

In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

1. Submit your observations of the chicken leg dissection.



2. Were you able to determine how the chicken moves?



3. What characteristics of muscles help you determine the direction of the movement?

Answers

Answer:

1. Submit your observations of the chicken leg dissection.

The first thing that I saw was the skin. This one has bumps on it. Underneath, when I carefully cut it, I could see a yellow layer which is fat. Under the fat, there is a thick pink tissue, the muscles. The muscle is in contact with the bones and attached to them by the tendons. They look thin and white and are at the muscles' ends since they attach them to the bones.

2. Were you able to determine how the chicken moves?

Yes, muscles work in pairs, so when I pull from a specific tendon, the leg bends since the muscle contracts to do this movement. Then this muscle will relax, another muscle will contract itself, and a tendon will pull the bone to return the leg to a straight position.

When one of these muscles contracts, the other relaxes to allow the bone's movement in a specific direction. Then this muscle relaxes and allows the leg's movement in the opposite direction since the muscle that was lax before now is contracting itself to extend the leg. There are a flexor and an extensor muscle.

3. What characteristics of muscles help you determine the direction of the movement?

The characteristics that help me determine the movement's direction were:

The position that the muscles have concerning the joints and the bones. The tendons at the end of the muscles and bones.

By following the muscle, the tendon, and where it is in the joint, I could determine the movement's direction.

Explanation:

When we observe a chicken leg dissection, we can determine the components that it has and how all the elements work together to move the leg. Even though the mechanism and structure are not the same as in a human body, we can see how muscles, bones, tendons, and joints work not only in animals but also in humans to allow movement.
