Answer:
The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.
Explanation:
Mitochondria are missing from root hair cells.
Root hair cells are specialized plant cells found in the roots of plants. Their primary function is to absorb water and minerals from the soil. To achieve efficient absorption, root hair cells have evolved specific structural adaptations.
Root hair cells are elongated and have a large surface area due to their elongated projections called root hairs. This increased surface area enhances their ability to come into contact with the soil, maximizing water and nutrient absorption. However, due to their focus on absorption and their short lifespan, root hair cells exhibit some structural simplifications, such as the absence of certain organelles.
One notable organelle missing from root hair cells is the mitochondria. Mitochondria are the "powerhouses" of cells, responsible for generating energy in the form of ATP through cellular respiration. Since root hair cells are mainly involved in absorption rather than energy production, they have a reduced need for extensive energy generation. As a result, they don't require as many mitochondria as other cells that are highly metabolically active.

The Centers for Disease Control (CDC) collect vast amounts of data. For this activity, we want you to use their Natality Information database to test various hypotheses about birth. For the following five issues, please create a hypothesis and then use the database to collect information about the issue. Once you the data is displayed, record it and indicate whether your hypothesis was supported by data.
The database functions in this manner:
Upon going to this website, you will need to comply with the CDC requirements for using the database. Because this is a school activity, you will be fine. Click I Agree.
The top section (Section 1) of the query engine will allow you to determine how your data sets will be displayed. You will want to Group Results by State for the queries you will perform.
Be sure to select the correct measure for your question/hypothesis. Select only one measure for each query.
Section 2 allows to select individual states or multiple states for comparison. If you have selected states in Section 1, you can run multiple data sets here and see them displayed by state. If you did not, the only way to see individual state data is to run the query one state at a time.
The remaining sections include the conditions you can use for comparison. You will need to find the appropriate section for the condition you are testing for. Once you have found it, go ahead and run your query by clicking Send.
Let me talk you through the process. Seriously, watch this video explanation of what you're doing.

A student is looking through a microscope at some cells of an onion root tip. Many of these cells are undergoing division since the root tip grows quickly and requires more cells. Which cell is going from metaphase into anaphase? W X Y Z
It's y
The cell Y is transitioning from metaphase to anaphase.
What is metaphase?
The chromosomes are at their second-most compacted and coiled state during the mitotic stage of the eukaryotic cell cycle, known as metaphase. These chromosomes, which contain genetic material, align in the cell's equator before being divided into the two daughter cells.
A phase of cell division known as "metaphase" (mitosis or meiosis). Individual chromosomes are typically dispersed throughout the cell nucleus. During metaphase, the cell's nucleus disintegrates and the chromosomes condense and migrate toward one another, aligning in the middle of the dividing cell.
The duplicate genetic material existing in a parent cell's nucleus is divided into two identical daughter cells during the third stage of mitosis, known as metaphase.

baby names connect to gender, and names flow from male to androgynous to female but never in reverse. the reason for this is that
In most cultural and religious doctrines, masculinity seems to be weighted well above the feminine gender. Hence, greater level of power or hierarchy is leveled towards the masculine gender. Hence, the reason for the trend in m naming pattern is due to the power alloted to male species.
Naming pattern usually follow the standard trend of having a root which is meant for the male kid, before transitioning to a fairly refined or similar name which is attributed to female kids. Intermediate names which can be used for either gender are called androgynous names sometimes precedes the female naming convention.Therefore, the pattern of naming with the masculine version coming first is due to the higher heirachical power given to males.
