Homologous structures are organisms which are grouped according to phylogeny, reveal that closely related organisms have more similar structures for example whales were once classified as a fish because they live in the water and they have flippers. Flippers are homologous to human arms and legs and they are therefore closely related to human beings.
Similar embryological development. Embryos of various vertebrates all look similar, including features. For example, tails which are not seen in the maturity suggests that all organisms evolved from a common ancestor, still, we express and share genes that are shared and belie ancestry.
Shared biochemical molecules such as DNA and ATP structure of molecules reflect descent with modification. The evidence of universal common ancestor is being reflected in the universality of DNA as a genetic material.
The genetic code in the machinery of DNA expression and replication. The relatedness within groups of organisms is reflected in the similarity in their DNA sequences. This is the exact pattern to be expected from diversification and descent from a common ancestor.
According to the research, the correct option is mood and emotions. When luana is nervous about a particular project, her <u>mood</u><u> and </u><u>emotions</u> affect(s) her ability to creatively solve problems.
<h3>What is nervous?</h3>
It is usually related to the emotional tension or turmoil that a person experiences.
It can refer to very diverse situations, it denotes insecurity in oneself in the face of certain pressures, which generate a large volume of expectations in those who must go through them, and the result is a kind of emotional overload in mood and emotions that prevents acting in a normal way in front of them.
Therefore, we can conclude that according to the research, the correct option is mood and emotions. When luana is nervous about a particular project, her <u>mood</u><u> and </u><u>emotions</u> affect(s) her ability to creatively solve problems.

Answer:
Most of the metabolic activities occur in the cytoplasm of the cell.
Cytoplasm is a gel-like fluid present within the cell. It consists of all the contents enclosed within a cell membrane excluding the nucleus.
It is mainly composed of water but also contains salts, enzymes, organelles, and organic molecules.
It is the main site for most of the cellular processes such as glycolysis (first stage of cellular respiration), protein synthesis, mitosis and meiosis etc.
Enable the cells to adjust or control gene expression when this is critical to their well being.
The correct answer for the question is B; Oxygen is used for respiration and carbon dioxide is a waste product.
Explanation;
Plants and animals use the process of respiration to produce energy which is used to fuel normal activities such as growth and movement. The process uses oxygen to break down nutrients such as carbohydrates, fats and proteins, and release energy needed by the plants and animals; but, also creates water and carbon dioxide as byproducts.
Carbon dioxide is a by product of the process of respiration, a chemical reaction that plants and animals use to produce energy they need to carry out day to day activities.
