structure of leaf is complementary to its function explain

Answers

Answer 1
The leaf has a thin lamina, mid rib and network of veins. The large surface area of the lamina helps in the absorption of light and its thin nature minimizes the diffusion process for gaseous exchange.Hope this will help
Answer 2

Answer:

All leaves have the same basic structure - a midrib, an edge, veins and a petiole. The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive. Plants provide food for all life on the planet.

CH2OH О, a CH3 H OH OH Н он Identify the macromolecule pictured above. O a Ob Protein Carbohydrate Lipid , ос Od Nucleic Acid​

Answers

Answer:

Although the pictorial representation is not clear but the question can be answered based on the known structure of each biomolecule. The answer is:

Carbohydrate

Explanation:

Carbohydrate is one of the four biological molecules in living systems. Carbohydrates are composed of long chains of carbon, hydrogen and oxygen in a 1:2:1 ratio i.e (CH2O)n empirical formula.

The structure of carbohydrate is composed of a ketone (C=O) or aldehyde (CHO) functional group and hydroxyll groups (OH). The simplest unit of any carbohydrate is called a monosaccharide. Hence, from the above structure in the question, which consists of long chain of carbon, hydrogen and oxygen atoms, it can be identified as a CARBOHYDRATE.

Object is not moving Answer 1 Choose... Object is moving towards observer Answer 2 Choose... Object is moving away from observer Answer 3 Choose...

Answers

Answer:

Object is moving away from observer.

Explanation:

If a force is applied to an object it starts moving. The object will move towards the observer, this is known as Doppler effect. It is when an observer or the thing under observation moves. There is change in its position due to a force exerted on it. The motion of the object also depends on the direction of force.

A surfactant is a chemical that disrupts hydrophilic/hydrophobic interactions, letting normally hydrophobic things dissolve in water (this is how soap cleans grease!). If I have a bunch of enzymes dissolved in water and I add a surfactant, what will happen to the enzyme structure

Answers

Explanation:

A good surfactant is going to have a hydrophilic head and a long hydrophobic tail. As a result, a surfactant molecule contains both an insoluble water (or an oil-soluble component) and a water-soluble component. Surfactant molecules will migrate to the surface of the water, where the insoluble hydrophobic group may extend out of the bulk phase of the water, either into the air or, if the water is mixed with oil, into the oil Phase, while the water-soluble head group remains in the water phase. This alignment and aggregation of surfactant molecules at the surface is intended to alter the surface properties of water at the water / air or water / oil interface.

How do the leaves help trees survive in their respective biomes? A. The temperate leaves are broad and flat to maximize sunlight absorption, while the taiga leaves are long and thin to minimize sunlight absorption. B. The temperate leaves are thin to minimize absorption of sunlight, while the taiga leaves are specialized to store water during the dry season. C. The temperate leaves shed water during the wet season, while the taiga leaves can enter long periods of dormancy during colder weather. D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing.

Answers

Answer:

The correct answer is option D.

Explanation:

The temperate leaves grow in temperate forests found in America, Europe, and Asia. This biome comprise of trees have evergreen conifers with needle like leaves. Such leaves can endure wide change of temperature and light. Some vegetation of temperate biome are conifers such as Pine, Hemlock and other. The trees shed their leaves with the beginning of fall and new leaves are delivered in late-winter  to protect from the cold.

On other hand, Taiga forest is the biggest biome on the planet. This biome contain conifers with long, slender waxy needles like leaves. These waxy leaves provide security against freezing temperature and from dying drying out. In contrast to temperate they don't sheds their leaves in winter and keep their needles throughout the entire year.

Thus, the correct answer is option D.

D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing

Describe and explain how temperature and light intensity affect the rate of photosynthesis?

Answers

Answer:

The rate of photosynthesis varies with light intensity and temperature.

Explanation:

The rate of photosynthesis varies with light intensity.it decreases as light intensity decreases and increase s as light intensity increases. However at much higher light intensity rate of photosynthesis becomes constant.

The rate of photosynthesis decreases with decrease in temperature.It increases as temperature is increased over a limit. But if light intensity is low increase of temperature has little influence on rate of photosynthesis.

Answers

Answer: The correct answer to the question is option B

INCREASES.

As human travel increases(As humans move from one place to another),the number of introduced species likely increases because as humans move from one place to another,they introduce new species of organisms to their new environment.

These non-native species grow in this new environment,becomes economically important and doesn't pose any harm to their new ecosystem unlike invasive species that poses a substantial harm.

The number of introduced species are likely to : ( B ) Increases

As Humans migrate from one place to another they introduce new species into their new environment naturally or artificially.

Migration

The movement of humans or any type of organism comes with the introduction of new species because as they move they take along with them certain species that naturally do not belong to their new environment.

The correct answer is option A "Duplication".

Explanation:

Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.

Answers

Answer:

D) The existence of Caulerpa is consistent with the cell theory.

Explanation:

This question describes species of algae in the genus, Caulerpa, which is a unicellular organism that possesses structures similar to leaves, stems and roots in plants. It also grows to a length of about 0.5metres. it reproduces sexually by fertilization of gametes (sperm and egg).

According to all these described characteristics of Caulerpa, it's existence is in conformity or accordance with the unified cell theory, which was proposed by three scientists namely: Matthias Scleiden, Theodor Schwann, and Rudolf Virchow in the 1830's. The three components of the cell theory states that:

1. Cell is the fundamental and basic unit of life existence.

2. All living organisms are composed of one (unicellular) or more cells (multicellular).

3. All cells come from already preexisting cells.

Hence, based on the components of the cell theory and the life pattern of Caulerpa i.e. Caulerpa is made up of one cell, it is made from the fusion of preexisting parental cells etc. It is consistent with the cell theory.

Answers

Answer:

The correct answer is - prevents lactose-utilizing enzymes from being expressed when lactose is absent from the environment.

Explanation:

The lac operon or the lactose operon is a operon that is essential for the many bacteria like Escherichia coli for metabolism and transport of the lactose.

In the presence of the lactose in the environment of the cell the lac genes are expressed due to the isomer of of lactose called allolactose binds to the Lac repressor protein and do not allow to bind it to lac operator. But in the absence of the lactose, the lactose utilizing enzymes are not expressed  due to repressor bind to the lac operator and prevents the binding of RNA polymerase to the promoter.
