Answer:

synovial

Explanation:

A synovial bursa (plural bursae or bursas) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint.

Answer:

Glycolysis

Explanation:

Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.

This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.

So, glycolysis is the process that all organisms do during cellular respiration.

Answer:

i want to say acid catalyst, but dont put that as your answer yet.

Explanation:

Answer: cellular respiration reverses the overall photosynthetic reaction, but less efficiently. The useful energy output of respiration is less than the energy input required for photosynthesis.

Explanation:

overall photosynthetic reaction

Light energy + 6CO2 + 6H2O —> C6H12O6 + 6O2

cellular respiration

C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (as ATP and heat)

Answer: Temperature and light

Explanation:

In winter, day length is shorter than in spring/summer and the sun does not rise as high in the sky. There is also more cloud cover, fog and snow to reduce access and intensity of light.

Colder temperatures reduce metabolic activity, and at temperatures below zero, water uptake is prevented, which reduces transport of nutrients, and icing of needles and snow cover reduce access to carbon dioxide.

In spring/summer sunlight is more readily available, temperatures more conducive to carbon dioxide uptake and transpiration.

The  two environmental factors are Temperature and light

stop condon mutation

Explanation:

The mutation is defined as the alteration or change in the genetic sequence of the chromosome. The mutations in the ADA genes have been noted and are caused by point mutations.

Point mutations are defined as the mutations in which the alteration of the single nucleotide of DNA occurs.

Stop codon mutations are the type of point mutations, in which the nonsense codons signal the end of protein synthesis.

Adenosine deaminase is involved in purine metabolism. It is involved in the development of the immune system.

Lucy's condition is due to the stop codon mutations in the genetic sequence of the DNA. The stop codon mutation will signal the end of the translation process, which will result in the non-functionality of the ADA enzyme.

Therefore, the stop codon mutation in the ADA enzyme will occur in Lucy's genetic sequence.

Explanation:

Answer:

D.It is a source of variation in sexually reproducing organism

Explanation:

Answer:

In the presence of light, chlorophyll (a substance that gives the leaves a green color) releases oxygen and produces carbohydrates, which enable the plant to grow. This complex process is called photosynthesis.

Explanation:

The roots are used to take dissolved mineral elements from the soil. The root is not capable of absorbing even the smallest organic or solid element. This means that it is important that the soil contains a certain amount of water, but also microorganisms, which have the task of decomposing organic matter and releasing the mineral elements from which it is composed.

Hello there! Photosynthesis

Objectives:

(Adaptable to grade levels 6-9)

The student will:

1. Observe evidence of photosynthesis in a water plant.

2. Assemble the equipment needed to measure the rate of photosynthesis in

elodea (water plant).

3. Count bubbles of oxygen gas given off by elodea to determine the rate of

photosynthesis.

4. Change the conditions of photosynthesis by altering light intensity and

carbon dioxide amount, and determine the effects on the photosynthesis rate.

5. Prepare a graph of the collected data and analyze it.

Materials Needed:

(For each group of four students)

elodea (water plant) lamp (40 watt)

test tube razor blade (single-edge)

dechlorinated water (room temperature) tape

sodium bicarbonate powder (baking soda) clock or timer

metal stand with rod or test tube rack metric ruler

Strategy:

PART A. Setting Up the Experiment

1. Obtain a sprig of elodea. Remove several leaves from around the cut end of

the stem. Slice off a portion of the stem at an angle and lightly crush the

cut end of the stem.

2. Place the plant into the test tube, stem end up, filled with water.

3. Secure the test tube to a metal stand with tape or place the test tube in a

test tube rack.

PART B. Running the Experiment

1. Place a 40 watt lamp 5 cm from the plant. After one minute, count and

record the number of oxygen bubbles rising from the cut end of the stem.

Count bubbles for five minutes. If bubbles fail to appear, cut off more of

the stem and recrush.

2. Run a second five-minute trial. Record and average your results.

3. Move the lamp so it is 20 cm from the plant. After one minute count and

record bubbles for two five-minutes trials. Again, average and record your

results.

4. Add a pinch of sodium bicarbonate powder to the test tube. Place the lamp

5 cm from the test tube. After one minute, record bubbles for two five-

minute trials. Average and record your results.

5. Prepare a graph of your results. Use the average number of bubbles for the

vertical axis. Use the type of environmental condition for the horizontal

axis.

Performance Assessment:

The students will answer these questions using specific values from the

investigation. Diagrams may be included.

1. How does this investigation demonstrate that plants give off oxygen during

photosynthesis? Explain your answer based on your observations.

2. How does the rate of photosynthesis change when the light source is moved

from a distance of 5 cm to 20 cm?

3. How does the rate of photosynthesis change when sodium bicarbonate is added

to the water?

Conclusions:

Plants use green pigments called chlorophylls to trap light energy. The

chlorophylls give a plant its green color. Inside the cells that have

chloroplasts, the light energy is used to make a simple sugar called glucose.

The process by which plants use light energy to make glucose is called

photosynthesis.

During this process of sugar production, carbon dioxide combines with water to

form glucose and oxygen is released. Oxygen that is produced in photosynthesis

is given off as a gas. If a lot of oxygen is being given off, photosynthesis is

occurring rapidly. If little oxygen is being given off, photosynthesis is

occurring slowly. The amount of trapped light energy and the amount of carbon

dioxide available affects the rate of photosynthesis.

The purpose of adding sodium bicarbonate powder to the water increases the

amount of carbon dioxide in the water.

This investigation can be performed with water plants grown in many parts of

the world, except regions that have permanent ice.

Return to Biology Index

The bubbles released by the Elodea signify that the plant is cycling matter because:

Carbon in the form of carbon dioxide is being fixed in the Elodea through the process of photosynthesis according to the following equation:

                      [tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]

During respiration by the same Elodea, the carbohydrate produced would be broken down in a reaction with oxygen to produce carbon dioxide and water:

                         [tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]

Thus, important materials such as carbon and oxygen are being recycled in the photosynthetic process.

Explanation:

Sister chromatids separate during anaphase II and mitotic anaphase is the statement most accurately states how the two types of cell division are alike. Hence, option D is correct.

Each chromosome is made up of two full-length DNA molecules joined at the centromere after DNA replication as part of cell division. They are two distinct DNA molecules known as sister chromatids.

Sister chromatids are two identical copies of the same chromosome that are produced by DNA replication and joined by a structure known as the centromere. They are divided during cell division, with one copy of each chromosome going to each daughter cell.

A chromatid is one of the two identical halves of a chromosome that has undergone replication ahead of cell division. The two "sister" chromatids are connected at the centromere, a constricted region of the chromosome.

Thus, option D is correct.

Answer:

A. inherit genetic instructions passed down from the same parents.

These animals are not related because they do not inherit genetic instructions passed down from the same parents. The correct option is A.

The transmission of traits and otherwise information through one generation of individuals or cells to the next is referred to as inheritance.

Inheritance can occur through one of two mechanisms: genetic inheritance or epigenetic inheritance.

Deoxyribonucleic acid is another name for DNA. It is the genetic structure that is in charge of storing information.

A nitrogen base, sugar, and phosphate backbone make up DNA. Inheritance occurs when genetic information is passed from a parent to a child, and thus from one generation to the next.

A gene pair's two alleles are inherited, one from each parent. Alleles interact with one another in various ways. These are referred to as inheritance patterns.

Thus, the correct option is A.
