Cell is the structural and functional unit of life
Answer:
A cell is the basic building block of all living things.
There are a few key differences.
• A plant cell has chloroplasts.
• A plant cell has a cell wall as well as a cell membrane while an animal cell only has a cell wall.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Please answer in at least 8 sentences and no scams
Answers
Answer:Improving your overall fitness can help you no matter what sport or other form of exercise you engage in. But where performance is concerned, the greatest improvements arise from training that develops skills specifically related to your activity of choice.
For instance, you need cardiovascular endurance and flexibility to play tennis. But to become good at tennis, you have to work on skill-related fitness components like agility, power, speed, and hand-eye coordination. It's this focus on activity-related skills that differentiate two distinct areas of fitness development.

Regardless of what sport or activity you participate in, improving your general fitness can benefit you. However, when it comes to performance, the best results come from training that focuses on developing abilities relevant to your chosen activity.

Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Answers
Well, I was taught about hypotheses differently but I'll try.
Answer: "If magnetic fields can repel and attract electric charges, then electric fields can exert a force on a positive charge because the electric field is radially outward from a positive charge and radially in toward a negative point charge."
I hope I don't mess up your grade and if I do then I'm extremely sorry.
Electric and magnetic fields can be demonstrated using electromagnets such as transformers.
What are electric fand magnetic fields?Electric fields are regions where electric force van be felt.
Magnetic fields are regions where magnetic force can be field.
If electric fields are force fields, then they can be felt from a distance by charges because force fields are felt from a distance.
If magnetic fields are directional, then north poles will repel north poles because like poles repel each other.

Beth wrote the following description of the life cycle of non-flowering, seed-bearing plants. Read her description and find the mistake.
"Non-flowering, seed-bearing plants go through four major stages in their life cycles. The first stage is when the plant is a seed from a cone. The second stage is when the plant sprouts out of the seed and the cones begin to grow. The third stage is when the plant is a seedling. The fourth stage is when the plant is a bigger seedling."
What statement corrects the error in Beth's report?
There are five stages in the life cycle of non-flowering, seed-bearing plants, not four.
The first stage is when roots will grow out of the seed and down into the soil.
The third stage is when the plant sprouts out of the seed and the flower grows.
The fourth stage is when the plant is an adult plant growing leaves and cones which produce more seeds.

A) They are used to store genetic information.
B) They are complex molecules made from smaller
molecules.
C) They are used to assemble larger inorganic
materials.
D) They are simple molecules used as energy
sources.
Answers
Answer:B
Explanation: Because if u Look at Protein Carbohydrates Nucleic acid and fatty acid actually they are polymers made up of small units called monomers.Option C is incorrect because these are organic molecules containing carbon so we cannot say that it will form an inorganic structures and the other option says about genetic information so genetic information is only determined by Nucleic acids not fatty acid, Protein or Carbohydrates and last option D is incorrect because nuclei acid didn't provide energy.
The statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
What are Nucleic Acids ?Nucleic acids are naturally occurring chemical compounds that break down to form a mixture of phosphoric acid, sugars, and organic bases (purines and pyrimidines). Nucleic acids are essential data-transmitting molecules of the cell, and, as they also direct the course of protein synthesis, they control the inherited characteristics of living things.
The two essential categories of Nucleic acids are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). DNA is the master prototype for life and contains genetic material in all free-living organisms and various viruses.
RNA is the genetic material of some viruses. It is also found in all living cells which plays an important role in certain processes like making proteins.
Thus, the statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).

Answer:
1.The probability of having purple flowers in the offspring is 75%.
A gene is the unit of inheritance found on the chromosomes. They often occur in pairs called alleles. A pair of alleles control the phenotype (observed traits) of an individual. Given two heterozygous parents that have purple flowers, let the gene for purple flowers be T and let the gene for white flowers be t. Using a punnet square as shown, there is a 75% chance of obtaining offspring having purple flower color
2.This means that each pea plant must have two sets of all genes, one inherited from each parent. For this mechanism to work, each germ cell must have only one gene set

This is a trait that distinguishes them from the invertebrates that have no spine and bone structure, like the octopus for example, or from the creatures that have an exoskeleton, which means they have a bone structure that is covering the body, but not inside the body itself, like the scorpions for example.
