The membrane has many passages through it. These passages chemically control what can enter or leave the cell. All eukaryotic cells also have cytoplasm. This jelly-like fluid fills the cell’s interior and contains thread-like proteins that help the cell keep its shape.

Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells. A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one unicellular to many trillions multicellular. I hope i helped you

the nerve impulse is an electrical current that travels along dendrites or axons.
Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.

Name the tissue which makes up the skeleton
Answer:
Bone, cartilage, tendons, joints, and ligaments
Explanation:
Uh that's what the skeleton is made out of. Nothing I can really explain
Answer:
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts. Bones also contain blood vessels, nerves, proteins, vitamins, and minerals. Also called osseous tissue.
A quick anatomy of the bone! (extras)
Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.

The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
to which part of a dna molecule are nucleotides added?
Answer:
Nucleotides are exclusively added to the 3' end of the developing strand when DNA is produced in the 5'-to-3' orientation. The 5'-phosphate group of the new nucleotide attaches to the 3'-OH group of the final nucleotide of the developing strand.
At the 3' end of the deoxyribose sugar, an upcoming nucleotide is added. The existing nucleotide's 3'-OH end and the new nucleotide's 5' phosphate make a phosphodiester bond. In this way, new nucleotides are added.
How does DNA polymerize?
The DNA is made up of nucleotides. Each nucleotide of DNA is made up of a deoxyribose sugar, a phosphate group, and a nitrogenous base. Nitrogenous bases include adenine, guanine, cytosine, and thymine. The sugar of the DNA has a lack of oxygen at the 2' end. A glycosidic bond connects the sugar's 1' end to the nitrogen base.
The 5' end of sugar is attached to the phosphate group. The 3' end of sugar is attached to the 5' phosphate of the new upcoming nucleotide. A phosphodiester bond is formed during the addition of new nucleotides. Two phosphate groups of the new nucleotides are removed. Example: If ATP comes, then it will make AMP and attach to the DNA chain.
Hence, at the 3' -OH end of sugar of the existing nucleotides, a new one is added.

what is the most durable part of the human body?
Answer:
the most durable and tough substance in your body is actually a tissue. Encasing your teeth and helping you chew, bite, and tear your food is your tooth enamel. That's the hardest substance in the human body.
Explanation:
The most durable part of the human body is Tooth Enamel.
What is Tooth Enamel?Tooth enamel is defined as the thin outer covering of the tooth that covers the crown of the tooth. This is the part that we can see outside the gums. This is the outer layer, the enamel is transparent. Dentin is the hard tissue that lies beneath the enamel, and is what gives teeth their color.
Once tooth enamel is damaged, it cannot be restored. Enamel can be restored to some extent by improving its mineral content. Enamel is the durable part of the human body.
While toothpaste and mouthwash can never "rebuild" teeth, they can contribute to this remineralization process.
Thus, the most durable part of the human body is Tooth Enamel.

Explain how the method of nutrition used by wild pine differs from the method of nutrition used by other organisms (animals)
Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.

2. Paired homologues align at the equator, microtubules attach to kinetochores of sister chromatids.
3. Microtubules shorten, chiasmata are broken, homologous chromosomes are pulled to opposite poles.
4. Nuclear envelope re-forms around each daughter nucleus.
5. Chromosomes condense, forming of spindle apparatus begins, homologous chromosomes pair and crossing over occurs.
The sequence of events in meiosis I is first 'chromosomes condense and crossing over occurs', second 'paired homologues align at the equator', third 'chromosomes are pulled to opposite poles', fourth 'separated homologues cluster at each pole' and fifth 'nuclear envelope re-forms around each daughter nucleus'.
Meiosis is a reductional cell division by which a parent cell produces four daughter cells with half of the genetic material.
Meiosis can be divided into meiosis I and meiosis II.

Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week on his Peloton bike. He gets 7-8 hours of sleep each night, but just can’t seem to stay awake during the day. Which organelle is most likely causing Marco’s problems?
Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.
The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.
ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.
In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.
