A group of students wants to study the rate of photosynthesis under various conditions. They use a blender to mechanically disru
11Alexandr11 [23.1K]

Answer:

B

Explanation:

The statement that best explains the result would be that <u>the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.</u>

The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.

It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. <em>The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light.</em> <u>This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate. </u>

The correct option is B.

Pepsi [2]

Answer:

So the mom has the genes of Ww because for the first kid not to get it she must have a recessive gene. The Father for sure has 2 recessive genes, ww, meaning the kid has a 50/50 chance. The kid could get Ww or ww.

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a
Agata [3.3K]

Answer:

2,855 is the size of the colony of mosquitoes after 4 ​days.

Explanation:

The law of uninhibited growth is given as:

A=A_o\times e^{k\times t}

A_o= Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

1300=1000\times e^{k\times 1 day}

k = 0.2623 day^{-1}

Population size of mosquitoes after 4 days

A_o=1000, k= 0.2623 day^{-1}

A =? , t = 4 days

A=1000\times e^{ 0.2623 day^{-1}\times 4 days}

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 ​days.

Can you define these words?? Thanks!
padilas [110]

Answer:

<u>Cellulose</u> - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

<u>Chlorophyll</u> - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

<u>Chloroplast</u> - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

<u>Bryophyte</u> - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

<u>Pterophyte</u> - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

<u>Gymnosperm</u> - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

<u>Cone</u> - A cone-shaped flower head of various plants like banksias and proteas.

<u>Angiosperm</u> - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

<u>Flower</u> - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

<u>Cuticle</u> - A noncellular protective covering outside the many invertebrates and plants.

<u>Vascular tissue</u> - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

<u>Xylem</u> - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

<u>Phloem</u> - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

<u>Roots</u> - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

<u>Root hairs</u> - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

<u>Stems</u> - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

<u>Leaves</u> - The green and flat organ that represents the most prominent feature of the most vegetative plants.

<u>Photosynthesis</u> - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).

Although the Cell Theory is widely accepted and well supported, what might happen to cause it change?
Sliva [168]

Answer:

By doing more research.

Explanation:

The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells.    With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
