Answer:

B. He was the first to observe live cells in a sample of pond water.

Explanation:

He was a self taught man that created the first microscopes which allowed him and others to see tiny organisms.

The other answers are not correct as Hans made the first microscope, cells existing in liquids were not a critical part of micro biology, and it was Schlieden and Schwann who created the cell theory that stated that all living things were made of cells.

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “Green pods” appear?

1.A and D  2.B and E  3.A,C and D  4.A,B,C,D and E

Answer:

3.A,C and D

Explanation:

As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.

As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Explanation:

Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.

The equation for cellular respiration is:

glucose + oxygen —> ATP + carbon dioxide + water

The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.

Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.

Answer:

With the help of warmth, oxygen, and good food from the soil, the seed will  open and sprout out. Once the leaves and roots will grow, the plant can go through the process of photosynthesis, the process that plants use to breathe and to make food using sunlight, during photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

The common feature between proteins, nucleic acids and carbohydrates is ; ( C ) They are all formed from the same elements.

Nucleic acids are present in the DNA or RNA of cells of living organisms. they practically store genetic information and they are made up of long chains of nucleotides.

Carbohydrates, nucleic acid and proteins are are made up same elements which are  ; carbon , oxygen and hydrogen that are combined in several ways in each of the compound.

Hence we can conclude that the common feature between proteins, nucleic acids and carbohydrates is they are all formed from the same elements.

Proteins, nucleic acids, and carbohydrates all have in common that they are all formed from the same elements. The correct option is C.

Carbon, hydrogen, oxygen, nitrogen, and, in the case of nucleic acids, phosphorus, are the same components that go into the formation of proteins, nucleic acids, and carbohydrates.

These substances make up the fundamental constituents of organic compounds.

The building blocks of proteins are amino acids, the building blocks of nucleic acids are nucleotides, and the building blocks of carbohydrates are simple sugars (monosaccharides).

These macromolecules all have the same elements, but having diverse forms and roles, highlighting the essential roles of carbon, hydrogen, oxygen, nitrogen, and phosphorus in biological molecules.

Thus, the correct option is C.

Answer:

cells of the body

Explanation:

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing

Growing economies increase demand.

Urbanisation increases demand.

The energy mix by fuel type.

Growth in vehicle demand.

This increased demand is caused in part by the increase in population, and by economic development. It is because these areas experienced large-scale economic development, there original energy sources were fossil fuels ,first coal and the oil and gas.

Answer:

Hey!

Some reasons for increasing the demand for energy is...

1) Increasing populations (more demands for heating and fuels)

2) Increasing industries (more factories mean more energy consumption / demand...

3) Increasing availability of different fuels (more choices means more use...)

a gamete produced in meiosis is the correct answer .

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.
