What is the result of a mutation during meiosis?
Answer:
A mutation is a change in the nucleotide sequence of the DNA in a cell. ... Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to the genetic variability of the population.

Why can't i view a specimen on a slide on the microscope
Explanation:
Specimen too dark if you place a large and dark specimen on the stage, then the light of the microscope is not able to pass though the object. You will not be able to see anything except a dark shadow without much detail. In this case you must either cut the specimen into thin sections, tear it apart or squash it.
What are the two types and functions of vascular tissue?
Answer:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle

A family decides to use their bicycles to get to the mall on weekends instead of driving a car. How is the family helping the environment?
The family is using less renewable resources.
The family is using less non-renewable resources.
The family is causing less fertilizer to enter the water.
The family is causing less trees to be cut down.
Answer:
The answer is B!
Explanation:
I know this because if the family was using less renwwable resourses it wouldn't be a problem. And if the family was causing less fertlizer to enter the water, that would be helping. So would causing fewer trees to be cut down. So it is all about the process of elimination! Hope I could help
A family decides to use their bicycles to get to the mall on weekends instead of driving a car, and the family is helping the environment by using fewer non-renewable resources, which is in option B.
What are non-renewable resources?Using bicycles instead of driving cars is an environmentally friendly choice because it helps reduce the consumption of non-renewable resources, such as fossil fuels, as fossil fuels are a limited resource that takes millions of years to form and their use contributes to air pollution and greenhouse gas emissions, which are major contributors to climate change. In addition to the environmental benefits, cycling can also have positive health impacts. Regular cycling can help improve cardiovascular health and reduce the risk of chronic diseases such as obesity and diabetes.
Hence, the family is helping the environment by using fewer non-renewable resources, which is in Option B.

He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter. For his first trial, Gavin shoots a 3.0-gram pea at the model. Its speed is measured at 12 meters per second as it leaves the straw. The pea does not break the paper towel, but it bounces back off and lands on the ground.eds that they can damage or puncture the sides of space vehicles. He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter.
Answer:
When the pea hit the paper towel, the paper towel applied an equal but opposite force on the pea.
Explanation:
A meteoroid is a piece of stony debris that float in space and move around the sun in different orbits and speeds in the Gavin experiment.
When the Meteoroids enter into Earth's surface?Meteoroids enter into Earth's surface with a high speed as shooting stars and called meteors. Meteors move through the atmosphere and landed on the surface and it is called a meteorite.

W
Inside of cell
Answer:
Explanation:
A cell membrane is composed of two phospholipid layers in which each molecule contains a single phosphate head and two lipid, or fatty acid, tails. The heads align along the inner and outer boundaries of the cell membrane, while the tails occupy the space in between. Only small, nonpolar molecules can pass through the membrane through simple diffusion. The lipid tails reject polar, or partially charged, molecules, which include many water-soluble substances such as glucose. However, the cell membrane is peppered with transmembrane proteins that provide passage to molecules that the tails would otherwise block.

a. What type of organism is the grass?
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
The grass is the producer of the food chain. Producers are the organisms in the food chain which produce food in a food chain.
What are the producers in a food chain?Producers are the organisms which make their own food in a food chain through photosynthesis. Producers are also known as autotrophs. They get energy to work from the chemicals or the sunlight, and with the help of water, these organisms convert the light energy into useable energy that is the chemical energy in the form of sugar or food particles. The most common example of a producer are the green plants.
Producers are any kind of green plants. Green plants make their food by taking sunlight and using this energy to make glucose (carbohydrate). The plant uses this carbohydrate, also called glucose to synthesize many products, such as wood, leaves, roots, and bark. Grasses are also an example of producers in a food chain as they produce glucose.
