Answer and Explanation:
Land - Lion
Water - Sealion
Flies - Bees
Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.
The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.
A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.

Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

Which goes where ? Mitosis Vs. Meiosis
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
This is because meiosis occurs in gametes and is used in reproduction.Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.Martime tropical air masses contain what type of air?

What happens during the 4 stages of mitosis
Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...

What is the law of dominance
What is the law of segregation
Answer:
Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. ... The recessive allele will remain “latent,” but will be transmitted to offspring by the same manner in which the dominant allele is transmitted.
What is the law of segregation- The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organsisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete

How is a renewable resource different from a nonrenewable one?
A. A renewable resource is more likely to run out.
B. A renewable resource can never be replenished.
C. A renewable resource has a higher demand
D. A renewable re purse is replenished faster than it is used
Answer:
Explanation:
d
A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.
What is a Renewable resource?A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?
Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.

Yes
Or
Not yet
Explain
The planet earth being a terrestrial planet is made up of rocks and hard rigid slabs of rocks called plates. These plates float on the flexible (asthenosphere) Mantel.
I understand that earth is a rocks planet and is made up of rocks and these rocks are called plates.
This uppermost layer or the crust of the lithosphere is composed of SIAL that is rocks made from aluminum and silicon, oxygen components. The layer lying below this is made from the semi-fluid matter called as upper mantel that is the asthenosphere which is partly molten and is said as molten rock. Due to the less dynamicity of this layer the above crust floats or drifts.Hence the water and soil in the lithosphere are characteristic of the crustal rocks.
