Where does fertilization of an ovum occur?

Answer:

Scientist Robert Hooke

Answer:

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

The stage of meiosis at which the alleles separate is anaphase. The correct option is B.

Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.

It entails two rounds of division, resulting in four cells with only one copy of each chromosome.

Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.

The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.

The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.

Thus, the correct option is B.

Reasons I would be concerned about eating GMO foods:

Explanation:

The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.

Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.

The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.

Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.

Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.

Answer:The interaction between Geosphere, atmosphere and hydrosphere: Geosphere interact with various spheres of earth and help in various cycles of element and performing different processes. One of the examples of such interaction is the geosphere interacts with the atmosphere and hydrosphere when a volcano erupts.

A volcano is a structure or the part of the geosphere which releases lava and particulate matter into the atmosphere where it plays a role as a center particle or nuclei for the water droplets which is come down into river and land in the form of rainfall which is a part of the hydrosphe

A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.

The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.

Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.

Thus, we can conclude that when a red onion cell is placed in salt water.

As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.

So, option (3) salt water is correct.

Answer:

cathode electrodes.

Explanation:

Electrochemical cells have two conductive electrodes, called the anode and the cathode. The anode is defined as the electrode where oxidation occurs. The cathode is the electrode where reduction takes place.

Explanation: Sieves are used to separate the solid smaller particles from a mixture. They are usually made of metal or fine plastic mesh, with openings between the wires that are sized according to the sizes of the desired particles in the mixture. Dried foods such as beans and rice are separated by using screens with openings of different sizes, small for whole grains, larger for cracked grains. Other kinds of products which require separation may be filtered through sieves, including sugar mixtures before they are packed or bottled.
