Answer:
Another evidence of evolution is the convergence of form in organisms that share similar environments.
Fossil record , comparative anatomy, DNA and molecular evidence and biogeography supports the theory of evolution.
What is theory of evolution?The theory of evolution is a scientific explanation for how living species have evolved over time and how new species have emerged. The hypothesis is predicated on the notion that all living things have a common ancestor and have evolved over time by natural selection.
Natural selection is the process through which specific features or characteristics, based on their capacity to aid people in surviving and reproducing in their environment, become more or less prevalent in a population over time.
The idea of evolution is largely regarded as the best explanation for the variety of life on Earth and is supported by a large amount of evidence from disciplines like genetics, palaeontology, comparative anatomy, and biogeography.

Answer:
Evaporation
Explanation:
since particles become free to move around in gaseous form, they are no longer close to each other.

How is salinity affected?
(a) evaporation increases
(b) freezing increases
(c) melting increases
(d) precipitation increases
Answer:
Salinity of seawater is affected by evaporation, precipitation, ice formation, and ice melting. Evaporation increases the salinity of seawater because when seawater evaporates, the salts are left behind, thus increasing their concentration. ... Ice formation and melting behaves in a similar way.
Answer: evaporation increases
Explanation:
the first person meant evaporation increases

Explanation:
A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
What is Dichotomous key?More details regarding the unique characteristics of a given organism are disclosed with each successive division. Once the organism no longer exhibits all of the chosen traits in concert with any other organism, it has been recognized.
In order to identify specimens with a dichotomous key, it is recommended to employ immutable traits (i.e. features that do not change). Size, coloration, and behavioral habits can all change across people and over the course of a lifetime.
Better traits are produced by physical features (like the number of limbs) and biological processes (like the mode of reproduction). Typically, dichotomous keys are displayed in one of two ways.
Therefore, A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.

a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

How do cells obtain energy?
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Which animal is more closely related to domestic dogs jackals or African wild dogs?
Answer:
Jackels
Explanation:
Domestic dogs and wolves are part of a large taxonomic family called Canidae, which also includes coyotes, foxes and jackals, according to the Integrated Taxonomic Information System (ITIS). Members of this family are called canids.
Golden jackals are more closely related to domestic dogs.
What are the characteristic feature of domestic animals ?These animals that have been bred selectively and genetically adapted over generations to live alongside humans.
These are distinct from the ancestor genetically.
Animal domestication is up three types like domestication for companionship, animals farmed for food and working or draft animals.
The domestic dog is a domesticated which is descendent from the wolf.
To make the animal as a domesticated, certain characteristics can be selected, such as the animals grow and mature quickly, breed easily, fertility times should be more.
The diet of the animals should be less expensive , like plant product eater animals. They should easily adopt the changing conditions.
They should live in herds, making them easy for humans to control.

Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as-
Answer:
nitrogen fixation, ammonification, and nitrification
Explanation:
The response enabled by auxin, a plant hormone, is known as phototropism.
What is phototropism?Phototropism is a phenomenon in which the growth and orientation of a plant is influenced by the direction and intensity of light. It is a crucial mechanism for plants to adapt to their environment and optimize their exposure to light for photosynthesis. When one side of a plant is exposed to more light than the other, auxin, a plant hormone, is produced in the shaded side of the plant. This causes the cells on the shaded side to elongate, resulting in the plant bending towards the light source.
The mechanism of phototropism involves the movement of auxin from the shaded side to the light-exposed side of the plant, where it inhibits cell elongation and promotes the growth of other cells. Phototropism is an essential process for the survival and growth of plants, as it allows them to optimize their exposure to light for energy production.

Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
