Name the living element of xylem.
PLZ ANSWER MY QUESTION IF U KNOW
Answer:
The xylem tracheary elements consist of cells known as tracheids and vessel members, both of which are typically narrow, hollow, and elongated. Tracheids are less specialized than the vessel members and are the only type of water-conducting cells in most gymnosperms and seedless vascular plants.
Describe how photosynthesis and cellular respiration are related in terms of oxygen. Describe the importance of the photosynthesis-cellular respiration system to living things.
This can be explained by analyzing the two chemical equations
The equation for photosynthesis is:
6CO2+6H20--->C6H12O6+6O2
The equation for aerobic respiration is:
C6H12O6+6O2--->6CO2+6H2O
The oxygen that is produced by the photosynthesis is consumed by the organism that do aerobic respiration.

How do organisms use carbon-based molecules and make water
C6H12O6+6O2--->6CO2+6H2O
This is the equation for cellular resipiration this is how organisms use carbon-based molecules(glucose) and make water
we have that from the Question"How do organisms use carbon-based molecules and make water" it can be said that
The Phenomenon of cellular respiration sees glucose catabolized into water H_2O
[tex]C_6H_{12}O_6+6O_2---6CO_2+6H_2O[/tex]
From the Question we are told
How do organisms use carbon-based molecules and make water
Generally the equation for how carbon-based molecules make water is mathematically given as
[tex]C_6H_{12}O_6+6O_2---6CO_2+6H_2O[/tex]
Therefore
It is seen that cellular respiration is the concept in play here
The Phenomenon of cellular respiration see glucose catabolized into water H_2O

In one year, 35 giraffes are born to a population. What does this number represent? growth rate emigration immigration birth rate
Answer:
birth rate
Explanation:fgyouyhgbfvtyoluhjjfygtpigubly
The number 35 represents the birth rate of giraffes in the population, specifically the number of giraffes born within a one-year time period and the correct option is option 1.
Birth rate is a fundamental demographic measure that quantifies the reproductive output of a population. It provides insight into the rate at which new individuals are added to the population through reproduction.
In the context of giraffes, a birth rate of 35 indicates that 35 offspring were born during the specified period. This information is crucial for understanding the dynamics of the giraffe population and its potential for growth.
Birth rates, along with other demographic factors such as death rates, immigration, and emigration, contribute to the overall population growth rate.
By examining birth rates over time and in conjunction with other factors, researchers can assess the sustainability and health of a population and make informed decisions regarding conservation and management strategies.
Thus, the ideal selection is option 1.

Why is an organism that reproduces asexually genetically identical to its parent
Answer:
Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.
Explanation:
Question 2
Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Answer:
Yes.
Explanation:
Yes, More beneficial genetic combination of the offspring has a positive effect on the survival of that offspring because due to more good characteristics the organism is able to survive harsh environmental condition and increases its survival rate. So we can conclude that presence of more beneficial genetic combination in the offspring greatly affect its survival in the environment among other offspring.

Explanation:
The smallest level of organisation in a multicellular organism is the cell. Multiple cells of the same type are organised into tissues which perform the same roles.
Different tissues come together to form an organ, which is made up of several different tissues that all work together to allow the organ to function.
Several organs come together to make up an organ system

Which of the following statements are true about mutations??
1-Mutations are random
2-Mutations are mostly beneficial
3-Mutations can occur in both DNA and RNA
for an organism
4-Mutations can only occur during interphase.
5-Not all DNA codes for proteins
6-Not all genes are turned on or activated
7-Substitution mutations typically result in frameshift
8-Mutations can be genetically inherited
Help!
*I think it is 1-2-4-5-7-8
Mutations are mostly random, Mutations may be found in DNA and RNA, Not all the DNA codes for the proteins, some genes are turned on or activated, Substitution mutations typically result in a frame-shift, They can be genetically inherited.
A mutation is an alteration in the genome of the organisms and may be formed in the RNA or the DNA. These can result from the changes in the genetic make up of the genes. They may also prevent the genes from functioning. Mutation is a process that involves the duplication in DNA through the genetic recombination. A type of genetic engineering.Hence these mutations are random, occurring both in DNA and RNA. Leading to changes in genetic codes and not all genes are activated. Some are inherited. Thus the correct statements are 1, 3, 5, 6, 7, 8.

What is the purpose of interphase in the cell cycle?What occurs during G1 and G2 in the cell cycle?
Answer:During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. In G1 the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication. In G2 division occur.
