Lacy wants to design an experiment that will show ovary part of a tomato flower grows into the tomato fruit.

The female reproductive organ present in flowering plants is the ovary. It is present in the flower's gynoecium. It is a portion of the pistil that holds the ovules and is located near the base of the sepals and petals. A single carpel or numerous carpels joined together can form the pistil.

Ovaries, as we know, are an essential component of the plant's female reproductive system. Well, the ovaries are where pollen is kept before developing into ovules and ultimately seeds. These seeds then germinate, causing the ovaries to grow and convert into fruits.

Even though the blooms are self-fertile, the pollen is nevertheless moved to the female half of the blossom by wind and the buzzing of bees' wings. The young tomato grows after fertilization, when the petals and stamens fall off.

So, Lacy will show ovary part of a tomato flower grows into the tomato fruit.

Answerand Explanation:

The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.

As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.

When a rock transforms into another type of rock, the scale at which these changes are occurring is at the atomic level, which is option D.

Rocks are composed of minerals, which are made up of different combinations of atoms. During the process of rock transformation, such as through the geological processes of metamorphism or igneous activity, the arrangement and composition of the atoms within the minerals change. This leads to the formation of new minerals and the alteration of the rock's properties.

At the atomic level, the atoms within the minerals may rearrange themselves, forming new bonds and crystal structures.

This can result in changes in the physical characteristics of the rock, such as its texture, color, or mineral composition.

The transformation may involve the loss or gain of atoms, leading to changes in the overall chemical composition of the rock.

Therefore, the changes occurring when a rock transforms into another type of rock primarily occur at the atomic level, as the atoms within the minerals undergo reorganization and bonding to create a new rock with distinct properties.

Therefore, the correct answer is D.

The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle

According to modern atomic theory, the proton can't move from one energy level to another

With the work of the English chemist John Dalton, the current atomic theory, which has continuously undergone refining, started to blossom at the beginning of the 19th century.

The modern atomic theory holds that atoms are no longer indestructible and now contain electrons, protons, neutrons, and other sub-particles. Isotopes are variations of an element's atoms that can exist.

The concepts of atoms and how they create matter are established by current atomic theory. Atoms are composed of negatively charged electrons revolving around a core nucleus made up of electrically neutral neutrons and more massive positively charged protons.

Fungus and protostomes have a more recent common ancestor than fungi and Archaea, which explains why they are more closely linked to one another. Compared to Protostomes, they are more closely connected to Archaea. Compared to protostomes, they are more closely connected to deuterostomes.

Animal kingdom organisms are categorised according to the development and form of their bodies. Those possessing bilateral symmetry as opposed to radial symmetry are considered true creatures. Radial symmetry is typically found in the more basic and frequently immobile creatures. The development of two embryological germ layers, the endoderm and ectoderm, is another characteristic of animals with radial symmetry, whereas the development of a third embryological germ layer, the mesoderm, is a characteristic of animals with bilateral symmetry. An additional characteristic of animals having three germ layers, known as triploblasts, is the existence or absence of an interior body cavity called a coelom. The presence of a coelom has various benefits, and depending on which tissue gives rise to the coelom, animals with one may be referred to as true coelomates or protostomes.

Explanation:

The Law of Original Horizontality is the aw makes you expect to find stratum D in sector 3.

The reason why there is no stratum D in sector 3 might be because of natural earth changes like geological events.

The Law of Original Horizontality is a basic rule in geology that says sedimentary rock layers are first put down in flat or mostly flat layers. This rule assists geologists in determining how rocks are placed in relation to one another in a geological formation.

So, If the rule that says rock layers are usually formed in flat, horizontal layers applies to this specific place we are studying, it means that layer D should be here in sector 3.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

The process of translating mRNA into the chain of amino acids that makes up the produced protein occurs on ribosomes in the cytoplasm of the cell.

The process of making proteins from an mRNA template is known as translation. Ribosomes are involved in the process of translating the nucleotide sequence on an RNA molecule into the amino acid sequence of a protein. A mature mRNA transcript is docked by ribosomes and tRNA, which then enlist many enzymes in an ATP and GTP-dependent process.

Ribosomes, intricate cellular components that hold both RNA and protein, are where translation takes place. Ribosomes are attached to mRNA when transcription is still taking place in prokaryotes (organisms without a nucleus). From the 5' end of the mRNA sequence to the 3' end, three bases are read at a time, and one amino acid from the corresponding transfer RNA (tRNA) is added to the developing chain until the entire protein chain is put together.

Answer:

For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.

Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.

In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.
