Justine is ice-skating at the Lloyd center what is her final velocity if she accelerates at a rate of 2.0m/s for 3.5 seconds?

Answers

Answer 1

7 m/s

Explanation:

Acceleration,

Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.

Making v the subject then

v=at+u

Taking u as zero then

Substituting 3.5 for t, 2 as a then

v=3.5*2=7 m/s

Answers

Answer:

Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.

Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.

The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.

Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?

Answers

Answer:

Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

Is meiosis sexual reproduction or asexual?

Answers

Answer:

Sexual reproduction

Answer:

Meiosis is sexual reproduction.

Explanation:

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

First question: When the population of lynx increases, the population of hares will decrease due to being over-hunted by more predators than usual. The hare is a source of food to the lynx, so with more lynx's...less hares... and less hares means either less food for the lynx and their population starts to die off...OR... The lynx adapt and start hunting new animals which could cause a massive disruption in the food chain.

Second question: When the number of hares increase in the environment it would mean more food for the lynx and other predatory animals. But with more food, comes more overpopulation. with plenty to eat the lynx population increases and that could cause problems for the environment, and other creatures.

Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.

Hope it helps uh...

The organelle that is responsible for storing and transporting nutrients through the cells is Vacuoles.

Vacuoles are also know as storage containers, they act as a storage organ in the body. This storage organ helps to transport food substances /molecules in the cell. Vacuoles are composed of enzymes, they help to hold water an food molecules. Vacuoles also help to remove waste substances that are harmful to the body.

The vacuole helps to keep balance in the body as they help to keep useful molecules and also get rid of waste substances.

It is possible because plants require other factors like sunlight and soil nutrients) other than Temperature and precipitation to grow

Plants require some Important factors for its growth and development and they are :

Temperature precipitation Sunlight soil nutrients type of soil

The two ecosystems with identical conditions of Temperature and precipitation might have differences in the amount of sunlight they receive and the Nutrients contained in its soil. therefore the ecosystems although similar can support different plants based on the difference in the amount of sunlight and Nutrients contained in the soil.

A. oil spills from ocean drill sites
B. human cities and houses being built in their habitats
C. Global warming
D. introduced can toads which are out competing polar bears for food

Answers

C. Global warming


Because of global warming the ice melts away but the polar bears need the icebergs in order to survive, without the icebergs the polar bears will lead to extinction. If global warming continues the ice will continue to melt and the polar bears won’t have any icebergs.
