Explain whether continuing to increase light intensity will increase the rate of photosynthesis. Please help!

Answers

Answer:

So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Explanation:

If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. The rate of photosynthesis decreases with light intensity. The rate of photosynthesis increases and then levels off.As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.

Lipids are...

A. Protein molecules

B. Similar to water molecules

C. Polar molecules

D. Nonpolar molecules

Answers

Answer:

The answer you are looking for is D.

Explanation:

Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. (non- polar molecules)

Lipids are fat molecules and are hydrophobic (water repulsive) in nature. Thus, option D is correct.

What are Lipids?

Lipids are important biomolecules and are widely distributed in biological systems. Lipids are organic macromolecules.

Lipids are insoluble in water (polar) and require non-polar solvents mainly hydrocarbons for dissolution like petroleum, ether etc. Thus, non-polar in nature.

Lipids include array of molecules like fats, wax, steroids, vitamins (fat-soluble; A,D, E and K), hormones, oils etc and have diversified functions.

Lipids form an integral part of the cell membrane. It also surrounds membranous structures. It protects the cellular membranes by creating an insulating layer.

Lipids are essential for storing and conserving energy in mammalian body. It helps in metabolism of glucose by converting extra glucose to glycogen in adipose tissues.

Lipids also act as transport molecules in the body. Many lipids function as chemical messengers.

Therefore, Lipids play a pivotal role in living system.

In what type of climate do trees produce narrower rings?

cool and dry
warm and wet
cool and wet
warm and dry

Answers

The answer is Cool and dry

Answer:

Cool and dry

Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.

Answers

Answer:

Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. ... Net primary production is directly related to ecosystem conditions.

Where does the water enter the plant in photosynthesis?

Answers

Answer:

The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

Lots of hydroxides (OH) will make a solution
A.acidic B. Basic C. Neutral

Answers

Answer:

B. Basic

Explanation:

Hydroxide (OH) is an anion with the chemical formula OH-. As the formula implies, it consists of an oxygen atom and a hydrogen atom. The more electronegative oxygen atom shares electrons with the less electronegative hydrogen atom via covalent bonding.

Hydroxide ion dissolves in water to form a very strong base, hence, an aqueous solution that contains lots of hydroxides will be BASIC or ALKALINE. A solution with lots of hydroxide ions is a STRONG BASE.

A mixture can be separated by all of the following EXCEPT
Filtration
Distillation
Sieving
A magnet
Evaporation
All are methods to separate mixtures

Answers

Answer:

All are methods to separate mixtures

Explanation:

A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.

Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.

Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.

Hence, all the methods listed are used to separate mixtures.

Answers

Answer:

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

Explanation:

This model in the image section is portraying the nitrogen cycle, which involves the transfer of nitrogen within biosphere, atmosphere, and lithosphere etc. The abiotic components of this model are the non-living parts while the biotic components are the living parts.

In this model, the movement of nitrogen from abiotic or non-living component of an ecosystem to the biotic or living component is as follows:

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

a student needs to find the density of a cube. each side of the cube measures 3 cm and the mass of the cube is 12g. what is the approximate density of the cube?
A. 0.4g/cm3
B. 2.25g/cm3
C. 4.0g/cm3
D. 36g/cm3

Answers

Answer:

Density = 0.4g/cm³

Explanation:

Given

Mass = 12 g

Length = 3 cm

Required

Determine the density.

To calculate density, we need volume.

Volume of a cube is:

Volume = Length ³

Hence:

Volume = (3cm)³

Volume = 27cm³

Density = Mass/Volume

Density = 12/27

Density = 0.4g/cm³ --- Approximated
