What are some of the consequences of acid rain? Thanku

Answers

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released, die of biodiversity in environment and other organism that supports decomposition of material

Why might a plant cell need to have a bigger vacuole than an animal cell?

Answers

Answer:

A plant cell might need a bigger vacuole than an animal cell because when a plant has stopped growing, there is usually one very large vacuole, sometimes taking up more than half of the cell’s volume; plants have a large sized vacuoles because it also provides turgidity and rigidity to the plant.

O regeneration
O vegetative propagation

Answers

binary fission- a single parent cell divides into two daughter cells eg amoeba,paramesium and bacteria

The given image asexual reproduction represents binary fission. The correct option is A.

What is binary fission?

In biology, fission is the division of a single organism into two or more pieces, followed by the regeneration of those parts into new, distinct organisms that resemble the original.

Asexual reproduction by splitting a body into two new bodies is known as binary fission.

When an organism divides into two halves (cytokinesis) through binary fission, it doubles its genetic material, or deoxyribonucleic acid (DNA), with each new creature acquiring one copy of the latter.

Divide into two is what binary fission refers to. It is the most straightforward and typical kind of asexual reproduction.

Thus, the correct option is A as it is showing the splitting of one cell into two.

. What is coir used for?

Answers

Answer:Coir, or coconut fibre, is a natural fibre extracted from the outer husk of coconut and used in products such as floor mats, doormats, brushes and mattresses.

Explanation:

What Is Coir?








coir is an organic product derived from the coconut tree. It is a fiber sourced from the tough, dense husk inside coconuts.





Two hands of coir based compost
Craig Knowles / Getty Images
Coir (pronounced COY-er) comes from coconuts. It's what makes up the fibrous husks of the inner shell of the coconut and is used for all sorts of products, including rugs, ropes, brushes, and even upholstery stuffing. You're probably most familiar with it as those stiff, scratchy doormats and the fibrous liners used in hanging baskets. Coir is very rot-resistant, making it perfect for outdoor products. It is also becoming increasingly popular as a potting mix and organic soil amendment.


For a coconut by-product, coir takes a good amount of effort to get to market. The outer husks are soaked until the fibers can be separated and then cleaned. Then they have to be sorted and graded by size. Dark brown coir is from the familiar mature coconuts, but there is also a white version. White coir is from immature, green coconuts and is finer and softer. Some manufacturers also dye the fibers.

Coir goes by many names. You may find it labeled as coir-peat, coco-peat, coir fiber pith, coir dust, and other similar-sounding brand names.

Horticultural coir is a peat-like substance that is used in gardening and agriculture. It is made from the pith found between the fibers. The coir pith gets washed, heat-treated, sieved to remove large particles, and graded. Very often it is compressed into blocks or bricks, which need to be soaked before using. You may also find bags or bales of coir. They can be hard to locate, but as coir becomes more mainstream, it should become more accessible and affordable.

Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomycotes Basidiomycotes

Answers

Answer:

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.

A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?

Answers

Answer:

This question lacks options, the options are:

A) FF and ff

B) FF and Ff

C) Ff and Ff

D) Ff and ff

The answer is D (Ff and ff for parent 1 and 2 respectively)

Explanation:

This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.

According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.

To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).

In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.

Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).

Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.

Explanation:

The process that the bacteria will use to obtain energy deep in the Earth's crust by cellular respiration. The correct option is A.

What is cellular respiration?

Bacteria use both aerobic and anaerobic cellular respiration. There are three major steps in aerobic cellular respiration: glycolysis and the citric acid cycle in the cytoplasm, and the electron transport chain in the plasma membrane.

The process of respiration in bacteria is carried out by mesosomes. Mesosomes are rolled up invaginations in bacteria's cell membrane.

Their purpose is to increase the required surface area for respiration. They are respiratory activity sites because they contain respiratory enzymes.

The process by which bacteria will obtain energy deep within the Earth's crust through cellular respiration.

A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?

Answers

Answer:

The average diffusion distance is 2.1 mm

Explanation:

Given

Diffusion distance of the four potato squares are;

[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]

Required

Average Diffusion Distance

To calculate the average diffusion distance; we simply calculate the mean of the student recordings

Mean is calculated as thus;

[tex]Mean = \frac{\sum x}{n}[/tex]

Where x is the individual distance of the potato squares

[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]

[tex]\sum x = 8.4mm[/tex]

n is the number of potato squares

n = 4

[tex]Mean = \frac{\sum x}{n}[/tex]

[tex]Mean = \frac{8.4 mm}{4}[/tex]

[tex]Mean = 2.1 mm[/tex]

Hence, the average diffusion distance is 2.1mm
