Transitional species are the species that are considered as intermediate. They are the species in between two contrasting species.

Archaeopteryx is considered as a transitional species because their fossils are in between dinosaurs and modern birds. Tiktaalik are also considered as transitional species because they are in between fish and and early tetrapod.

Transitional species supports the theory of evolution. The fossils found are considered as evidence for evolution. Transitional fossils are debris of species that are present in between ancestral species and modern species.

Answer - Options 1, 2, 3, and 4.

The last option is not correct. Transitional species does not contradict the theory of evolution. It supports the theory of evolution. Transitional fossils are evidence for evolution. Transitional fossils are debris of species that are present in between ancestral species and modern species.

Digestion is the process by which the digestive system assimilates the necessary substances (energy, minerals and vitamins) from the food consumed, which then are transfered by the circulatory system to every cell of the body.

The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks. They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth.

Scientists divide Earth's entire 4.6 billion years into four major time periods. The oldest — and by far the longest — is called the Precambrian. It is divided into Eons known as the Hadean (HAY-dee-un), Archean (Ar-KEY-un), and Proterozoic (Pro-tur-oh-ZOE-ik). After the Precambrian come to the Paleozoic Era and Mesozoic Era.

In interpreting rock age the use of relative dating puts the sequences of rocks layers into chronological order. Although the layers are no longer horizontal, geologists are able to determine their order.

Examples interpreted from rock strata provide a way to organize Earth's history. Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. phenomena can be observed at various scales using models to study systems that are too large or too small.

After seeing variations in the fossils as they moved from oldest to youngest sedimentary strata, geologists came up with the geologic time scale. Relative dating was used to split Earth's history into periods when comparable creatures were present.

Relative dating is used to chronologically organize the strata of rocks in order to understand rock age. Geologists can still discern the sequence of the strata, despite the fact that they are no longer horizontal.

Earth's history may be organized using examples derived from rock layers. The fossil record and the analysis of rock layers only reveal relative dates an absolute scale is not provided.

Therefore, to examine systems that are too huge or too tiny, events can be seen at multiple sizes using models.

Explanation:

To answer this question we need to remember come concepts first, cloning implies that an identical genetic individual is created, meanwhile, selective breeding means that only the members of a population that exhibit the desired trait will be crossed, which left us hybridization, this involves a cross between species or varieties, therefore this is the correct answer (option B).

Well, first we have to consider that when we talk about positive and negative feedback, usually we refer to homeostasis, which's a kind of balance our bodies do regarding physiological processes.

Having this in mind, we use the term negative feedback to signal the balance of nutrients (e.g. oxygen, minerals), pressure, and temperature, our blood does to achieve the normal equilibrium of this in our body.

In the same way, when we say positive feedback, we refer to those processes that our body carries out to keep or maintain the influence of a stimulus.

The butterfly begins its life as a larva or a caterpillar. A caterpillar molts as it grows. When it reaches its full size, it forms into pupa and undergoes metamorphosis where the butterfly begins to form. A grasshopper however, is an insect that undergoes incomplete metamorphosis where it hatches from an egg and goes through the three nymphal stages. Each of the nymphal stage shows a smaller version of the insect and becomes larger as it grows. The third stage will show the adult form of the grasshopper.

The environment can either be biotic or abiotic. These make up an ecosystem. The community of living organisms in an ecosystem is making an interaction with their abiotic environment as well as with the other living organisms present in the ecosystem.

Answer - False

When the DNA or RNA sequences are altered, the resultant amino acid can occasionally change as a result. A completely new sequence of amino acids may be produced as a result of how the ribosome interprets the mRNA sequence.

The amino acid sequence of the protein that the gene codes for can be altered by changes to the DNA sequence of that gene, a process known as mutation. A single DNA letter can change in a point mutation. They can be divided into three categories: Missense mutations alter a protein's single amino acid. DNA sequence modifications are known as mutations. Viral infection, mutagen exposure, or errors in DNA replication during cell division can all lead to mutations.

As a result, option C, which reads: "A change in the DNA sequence affects the RNA sequence, which occasionally results in a change in the resultant amino acid," is the right statement.

Kudzu can be considered an autotroph because kudzu vine can cover forest plants and kill them by competing with them for sunlight. This vine has a significant impact on forest ecosystems.

Kudzu spreads swiftly and out of control by runners (stems that root at the tip when in contact with moist soil), rhizomes, and vines that generate new plants by rooting at the nodes.

Kudzu grows at a rate of one foot per day after it is established, and its mature vines can reach a length of 100 feet. Fast-growing invasive plants like kudzu outcompete anything from native grasses to fully developed trees by blocking the sunlight needed for photosynthetic activity.

All the processes in the question requires energy, but the only one that does not occur in plants is the 1. Locomotion, since a plant do not move on its own.

The three main differences between plant and animal cells are:

1. Plant cells have a cell wall, a structure that's located outside the plasma membrane to protect the cell. Animal cells will never show a cell wall.

2. Plant cells have chloroplasts, organelles needed for photosynthesis to take place. This is what makes a plant an autotroph. Animal cells will never show a chloroplast.

3. Plant cells do not have centrioles and centrosomes, but animal cells do. Also, plant cells always shows one or a few large vacuoles, while in animal cells vacuoles are small and in a large number.

Abiotic factos are non-living chemical and physical parts of the environment that can affect the ecosystems and the living organims. The depth of a body of water, climate, width of a body of water and the seasons are all abiotic factors.

Answer

Cells

Explanation

All living things, plants and animals are made up of cells.

A cell consists of three basic parts, 1. a nucleus - which is the center of the cell, and it contains chromosomes that carry genetic information. 2. a cytoplasm which is the medium for all the organelles, it consists of water and salts which makes up the solution that enclosing the cell. 3. the cell membrane, which is used by the cell to sepate the inner part of the cell from the outer part. So the cell consists of many other organelles like mitochondria.

The movement of water in celery happens because of the capllary action in the xylem, the water moves up from the roots through the stem and into the branches and leaves. Therefore, the answer for the question is A (the water would be flowing upwards towards the leaves).

To answer this question we need to remember a bit of the earth's history. In the first stages, Precambrian, on earth, there was no oxygen, nonetheless with the rise of photosynthesis by cyanobacteria the concentration increased, nonetheless it was a gradual process, now also there was an increase in carbon dioxide levels at the end of the Mesozoic due to intense volcanic activity along with other factors. So taking this into consideration we can say that the correct answer is the third option, as a volcano is a sudden event and if large enough maybe it won't change all the atmosphere, but can generate a local change.

In the question the options that are density-dependent factors (biotic factors) are:

- Disease;

- Predation;

- Competition for food;

- Competition for light.

All the other options are abiotic factors that can happen by events related to the geography and climate of the habitat.

It is a false statement that ATP synthase converts ADP into sugars. It converts ADP to ATP.

The ATP synthase is an enzyme that is responsible for the production of ATP from ADP. The term ATP is adenosine triphosphate while the term ADP is adenosine diphosphate.

We know that the enzyme ATP synthase  is a precursor, in the presence of the precursor, there is the conversion of the ADP into ATP which is the energy molecule of the living cells.

Using gene drive to control on invasive species could damage the environment in ways that are very hard to predict, by causing unintended consecuences.

For example, while intending to affect only a local population, gene drive could spread to an entire species by the return of any individual of the species to its original habitats. This could be by migration, accidental human tranportation, intentional relocation or a different way. If this happens it would drive the entire species to extintion causing damage to the ecosistem as it would affect other species that interact with the original.

It is important to acknowledge that the use of gene drive has permanent consecuences and that it is very hard to predict the effect it will eventually have in the ecosystem.

Also, there are ather ways that sould be considered to control invasive species such as the intentional manipulation of natural enemies, use of pesticides or herbicides, manipulation of the habitat to increase mortality, etc.

Moreover there is the possibility of affecting other non-target species that are able to interbreed with the original, causing a permanent damage in the ecosystem.

In conclution, the risks of gene drive may not be worthy, specially because the damage will be permanent and the real effect it will have is extremly hard to predict.
