Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.
Explanation:
Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.
What are analogous structures?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.
While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).
Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

How do Demetri's results show that digestive enzymes are crucial to maintaining homeostasis inside the body?
In addition to breaking down food so that the nutrients may be absorbed, enzymes also generate vitamins like biotin and vitamin K and protect the body from dangerous microorganisms.
What is homeostasis?A biological system's ability to self-regulate and maintain stability while responding to shifting environmental factors is known as homeostasis.
The body needs a steady supply of nutrients from food that has been digested. They are crucial for maintaining health and carrying out bodily tasks. The body may absorb and use food that has been broken down by the digestive system.

Describe the process of cell division in a plant cell.
Answer:
Cytokinesis in a plant cell: the cell plate forms down the middle of the cell, creating a new wall that partitions it in two. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis.

Give an example of how water acting as a solvent is important for living organisms.
Answer:Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.

CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?
2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?
4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)
Answer:
1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.
3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

Which statement is true about the law of reflection?
The angle of reflected light is the same as the incoming angle of light.
The angle of reflected light distorts the image to appear larger or smaller.
The angle of reflected light is smaller than the incoming angle of light.
The angle of reflected light is larger than the incoming angle of light
Answer:
The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.
The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.
The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.
Law of reflection is defined as:
The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
What is Reflection of Light?
The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.
Explanation:
Answer: The angle of reflected light is the same as the incoming angle of light.
Explanation:
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. The angle of reflection is equal to the angle of incidence.
MITOSIS
Complete the sentences below by circling or filling in the correct words.
Mitosis is cell division of (germ, somatic) cells. The purpose of mitosis is to create new cells for
and
Mitosis produces four (different, identical) cells that are (diploid,
haploid)
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
Involves one cell division?
Results in two daughter cells
Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)
Daughter cells are genetically identical
Occurs in all organisms except viruses
Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm)
Prophase is much shorter
No recombination/crossing over occurs in prophase.
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
