A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
The sun provides the energy for photosynthesis. Cells use sugar as a source of energy. The products of cellular respiration are CO2 and H2O. These products are used by plants to make sugar and oxygen through photosynthesis.
Answer:
The correct answer will be option-B
Explanation:
Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.
Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.
The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.
Thus, Option-B is the correct answer.
Solar Distance:
The solar distance is the distance<span> between the Earth and the Sun. Since the Earth rotates, the distance changes.
</span>
Air Pressure:
The air pressure/atmospheric pressure is <span>the pressure spent by the weight of the atmosphere.
</span>Latitudinal Location:
the latitudinal location is used, with longitude, to specify the exact location<span> of features on the Earth surface.
</span>
Water presence:
The water presence is the existence of water.
There are many factors that influence the weather but the 4 main ones are solar distance, air pressure, latitudinal location, and water presence.
I hope this helps!
Answer: Sexual reproduction: rabbits and dolphins.
Asexual reproduction: Strawberry and potato.
Explanation:
- Sexual reproduction is carried out with the participation of germ cells from two stem organisms - female and male, which transfer the properties of the inherited material to the new plant. The main characteristic of sexual reproduction is the division of the relative fusion of male and female sex cells. The end product of this relationship is the creation of an organism that contains the genetic information of both parents.
- Asexual reproduction is a habit that produces an organism identical to the parent organism, and we call this product clones. This form of reproduction does not involve the germ cells and may occur by division or budding. Many types of plants reproduce in this way. So the strawberries are propagated by boils, and the potatoes are buds from the tub
