What is cell cycle ?During a cell's growth and division, a set of processes known as a cell cycle occur. In what is known as interphase, a cell spends the majority of its time expanding, replicating its chromosomes, and getting ready to divide. Following the cell's exit from interphase, it goes through mitosis to finish dividing.
These are the prophase, prometaphase, metaphase, anaphase, and telophase phases. It is sometimes referred to as the sixth phase of mitosis since cytokinesis is the final physical cell division that occurs after telophase.Learn more about Cell cycle here:

A.
They would learn how to photosynthesize.
B.

C.

Answers
A stream of water holds thriving bacteria. If drought conditions caused the stream to dry up, they would produce endospores. The correct answer is option D
Why do bacteria produce endospores?
Endospores are external structures produced by bacteria when harsh conditions are present. This survival skill ensures the bacteria survives a harsh condition such as high temperatures.
The bacteria forming an endospore would be able to survive unfavorable environmental conditions such as when the stream dried up.
In summary, when the stream dried up, it exposes the organisms that lives in the stream to heat, and lack of water. Under this condition, most organisms would die, but the endospores produced by the bacteria living in the stream would ensure it survives that condition until water returns to the stream.

The number of diploid chromosome in hybrid plant will be 22 .
Haploid refers to the presence of a single set of chromosomes in an organism's cells. Sexually reproducing organisms are diploid having two sets of chromosomes, one from each parent. In humans, only the egg and sperm cells are haploid.
Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The term diploid refers to two sets of chromosomes resulting from the union of the sperm and the egg. This is typically the number of chromosomes found in the nuclei of body cells of a plant or animal. In plants, the diploid part of the life cycle is called the sporophyte.

4. The early atmosphere was high in O2 and low in CO2 so until photosynthesis could produce large amounts of carbon dioxide, organism had to use anaerobic respiration.
Answers
The statement that supports the idea that anaerobic respiration existed prior to aerobic respiration in the history of our planet is: (2) The early atmosphere was high in CO₂ and low in O₂ so until photosynthesis could produce large amounts of oxygen, organism had to use anaerobic respiration.
Anaerobic respiration is the process of releasing energy by the breakdown of glucose but without the involvement of oxygen. This process synthesizes less energy than the aerobic respiration. However, the organism in the early earth were adapted to such environment of high carbon dioxide and therefore could perform anaerobic respiration.
Photosynthesis is the process of synthesizing one's own food. This process releases oxygen and is performed by aerobic organisms like plants, algae, etc.

Explanation:
You want to know the height of a 1:800 model of an 80 m (8000 cm) giant sequoia tree.
Scale factorThe scale factor of a model or drawing or map is the ratio of a dimension of the model to the corresponding real world dimension. That is, the model dimension is found by multiplying the real world dimension by the scale factor.
model height = 1/800 × tree height
model height = 1/800 × 8000 cm = 10 cm
The model of the sequoia tree would be 10 cm tall.

A milder climate will reduce the durability of building materials and affect the indoor climate of buildings. Warmer summers will introduce a greater need for cooling.
An engineer needs to consider the insulation and stable temperature. Insulation levels differ in heating/cooling systems designed for a house found in a warmer climate from that of a cooler climate.
What is designing a heating/cooling system?For energy efficiency, each component's position is essential. As soon as feasible during a facility's development or re-fit, design your HVAC system. HVAC systems can operate more effectively if the building can be modified and insulated.
There are two classifications for HVAC systems: ducted and ductless. To cool or heat a building, the main unit of a ducted system forces air via a network of air ducts.
On the other hand, ductless systems don't have air ducts and employ different techniques to spread clean air across a room. Hence, insulation is different in the heating/cooling system.

Answers
E) Their core target market has grown
Prairie dogs play a significant role in the ecosystems they live in. They have an impact on grasslands both directly and indirectly due to their grazing, burrowing, and role as prey.
How do prairie dogs change with the surroundings?Some of their physical modifications have given them the ability to thrive at what they do. Burrow-digging is made easier for them by their long-nailed toes and short, powerful arms. Despite having tiny legs, prairie dogs can travel short distances at speeds of up to 35 mph in order to flee from predators and reach the safety of their burrows.
The prairie dog is a keystone species because it is essential to the health of the entire ecosystem in which it lives. The reason for this is that prairie dogs are able to make the soil more fertile, improving the conditions for plant growth and benefiting herbivores. They also reproduce quickly and serve as prey for a variety of predators, thus they are in high demand.

Fish that can survive the lower oxygen levels undergo natural selection. These fish will reproduce and proliferate.
The water's lower oxygen levels will impact fish respiration. The fish may relocate to a better area with more dissolved oxygen in order to adapt to the change. However, because the fish are still the same genetically and phenotypically, there is no connection to the process of natural selection.

Answers
Answer:
Chitin
Explanation:
Which polysaccharide is an important component in the structure of insect and fungal cells?
Chitin is a big, structural polysaccharide made up of chains of modified glucose that serves as a structural protein. Among the invertebrates and fish, chitin is found in the exoskeletons of insects, the cell walls of fungus, and some hard structures in their exoskeletons. Chitin is only second to cellulose in terms of abundance, with cellulose being the first.
Which polysaccharides are important for structural support in animals and plants?
Polysaccharides are mostly used for one of two purposes: energy storage or structural support, depending on their structure. Starch and glycogen are both very compact polymers that are utilized to store energy in the form of carbohydrates. Animal and plant cellulose, as well as chitin, are linear polymers that provide structural support in both plants and animals, respectively.

a model rocket is accelerating at 2m/s square. the force on it is 1N what is the mass of the rocket? with explanation plsssss
Answers
The mass of the model rocket accelerating at 2m/s² with a force of 1N in it will be 0.5 kg.
Force (F) is the external component that has the capability to change the state of motion or rest of a body. The formula for force is mass of the body (m) multiplied by its rate of acceleration (a).
F = m.a
Acceleration is the rate of change in the velocity of an object with change in time.
According to the question,
Force = 1N or 1 kg⋅m/s² ( 1 N = 1 kg⋅m/s²)
Acceleration = 2m/s²
The formula can be written as: m = F/a
Therefore, m = 1 kg⋅m/s² / 2 kg⋅m/s²

How has bumblebees organism evolved?
Answers
Bumblebees are believed to have originated from hunting wasps that developed a liking for honey and opted to go vegetarian.
Bumblebees likely evolved on Earth at the same time as flowering plants during the Cretaceous period, between 146 and 74 million years ago, but fossil evidence is scant.
What modifications have bumblebees undergone?Bumble bees are accustomed to cold weather, which is one reason why they are more prevalent there. This indicates that they have certain adaptations—the most notable of which is their thick, fluffy hair—to stay warm in chilly climates. They may also be less able to cool themselves in hot weather due to these adaptations.
About 30–40 million years ago, the first bumblebees broke into this realm of giants. This coincided with a time when the weather was colder, which may have encouraged bees to become bigger and furrier.
Bumblebee looks up to Optimus as a mentor and a father figure. They previously worked together during the conflict on Earth and on Cybertron.
