4. Which of the following does not make up a bronchi?
a. cartilage
c. smooth muscle
b. mucous lining
d. pleural membrane​

Answers

Answer 1

Answer:

c. smooth muscle

Explanation:

The cartilage and mucous membrane of the primary bronchi are similar to that in the trachea. As the branching continues through the bronchial tree, the amount of hyaline cartilage in the walls decreases until it is absent in the smallest bronchioles. As the cartilage decreases, the amount of smooth muscle increases.

If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have
A
100% white flowers
B
75% purple flowers and 25% white flowers
с
50% purple flowers and 50% white flowers
D
100% purple flowers

Answers

im pretty sure it would be c

If purple-flowered  plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first  generation of offspring should have 100% purple flowers.

Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.

In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.

Explanation:

oxygen aids in glucose production through respiration and supports the organism since glucose is the food for plants

The role of oxygen in photosynthesis and in cellular respiration - B Oxygen is released in photosynthesis and used in cellular respiration to produce energy.

Role of oxygen

1. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.

               6CO₂ + 6H₂O+ energy → C₆H₁₂O₆ + 6O₂

2. In respiration, the product of photosynthesis, glucose and oxygen are converted into carbon dioxide, water, and energy and oxygen is used to break down glucose

                C₆H₁₂O₆ + 6O₂ →   6CO₂ + 6H₂O+ energy

a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

Answers

Answer:

There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:

d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

Explanation:

Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.

Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.

These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

Which of the following did you remember?

Answers

Answer:
All statements are true and explain the function of most organelles present in the cell.
Explanation:
I remember the following:
-The nucleus directs cell activity: the nucleus is where the genetic information is found and by means of gene expression it controls the cellular functions.
-Ribosomes produce proteins for the cell: Ribosomes make messenger RNA proteins (mRNA) by connecting amino acids together
-These proteins are then moved through the cell by the endoplasmic reticulum: it is a network of membranes within the cell through which proteins and other molecules move
-The Golgi apparatus packages and distributes proteins from the endoplasmic reticulum: It transforms and exports protein to the rest of the body. Proteins, in their passage through the Golgi apparatus, carry out a modification process.
-Vacuoles store water, waste products, food, etc: vacuoles store substances, in plants they occupy a large percentage of the cytoplasm and change their size during ormoregulation.
-Lysosomes break down waste material and debris: They contains hydrolytic enzymes that allow intracellular digestion of macromolecules
-Mitochondria break down sugar molecules to supply energy. Similarly, chloroplasts capture the energy from sunlight and convert it into chemical energy: Chloroplasts and mitochondria through the processes of cellular respiration and photosynthesis produce energy necessary for the vital functions of the cell.
-The cell membrane protects the cell and controls what enters and leaves it. The cell wall supports the cell membrane, maintains the cell’s shape, and protects the cell. The cytoplasm supports and protects organelles in the cell: The membrane is the support of the cell and through it there is exchange with the external environment. The cytoplasm is the one that supports the rest of cellular organelles

Answer:

plant and eukaryotic cells (B)

Explanation:

animal cells have a cell membrane but no cell wall and prokaryotic organisms lack a nucleus or any other membrane bound cell organelle.

Plant and prokaryotic cells definitely have a cell wall. So, the correct option is C.

What is Cell wall?

Cell wall is defined as the structural layer that consists of polysaccharides and is present outside the plasma membrane which can be rigid, rigid and flexible. This provides protection to the cell from external factors that may be harmful to the cell and also provides structural support.

Plant and prokaryotic cells definitely have a cell wall. The cell wall of a prokaryotic cell is present under the capsule while the cell wall of a plant cell is a specialized form of extracellular matrix that surrounds each cell of a plant. This provides structural support to the cell and protects the cell against infection and mechanical stress
