The correct answer would be- reduced human interference to the habitat.
Explanation:
The Tundra Biome is a biome with an extremely cold region with little precipitation, short growing seasons, very poor nutrients. The Tundra biome is at risk due to global warming, which harms, plants and animal species and the ecosystem of the biome.
low carbon emission by reducing planet-warming pollutants by reducing the fossil fuels is key to safeguarding Earth's tundra habitats and liting industries are the
Answer: Tundra is the coldest biome on Earth.
Explanation:
It has become sensitive to the trend of global warming the surface air temperature has risen by 0.9 °C. Many regions have experiences the record breaking high temperature in otherwise winter months since 20 century. Tundra natural fires release carbon dioxide gas in the atmosphere. The climate of Tundra can be changed by human efforts. Some activities like reducing the use of fossil fuels which release green house gases like carbon dioxide, and others which warm up the atmosphere, banning the industrial activities nearby regions, and protection of certain species affected by the rising temperature.
As we know that the leaves of plants are waterproof due to cuticle. On the same way, take
some pieces of paper of leaf size and make them waterproof. After completion, put half of these
paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof?
Explain your observations and results with justifications
Answer:
No.
Explanation:
No, all the pieces of paper did not remains waterproof because expansion of paper occur due to high temperature of hot water. We know that materials expand when they experience high temperature and contract when they observe cold temperature. So the pieces of paper remains waterproof which were put in cold water while those were not waterproof if they are put in hot water.

A plant growing toward a light source is an example of an organism..
A: attracting a mate
B: destroying infectious germs
C: responding to external stimuli
D: obtaining moisture from the air
Answer:c
Explanation: The plant is responding to external stimuli by growing toward light like our eyes adjusting to the light in the dark......................
The correct answer is option c i.e. responding to external stimuli (phototropism).
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
what is phototropism?
Phototropism is one of the many plant tropisms or movements which respond to external stimuli.
Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.
Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light.
Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.
hence , a plant growing towards a light source is an example of phototropism.

conduction of water by root pressure and suction pressure
Answer:
Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.

Explain the difference between a diploid and a haploid cell.
can sum1 tell me the difference plzzzz
Difference Between Haploid And Diploid
Haploid cells contain only one set of Chromosomes (n).
Diploid, as the name indicates, contains 2 sets of chromosomes (2n).
A-Haploid cells are formed by the process of meiosis.
Diploid cells undergo mitosis.
B-In the higher organism, such as humans, haploid cells are only used for sex cells.
In the higher organism, such as humans, all other cells beside sex cells are diploid.
C-Examples of haploid cells are gametes (male or female germ cells).
Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells

B. Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
Sunlight as an Electromagnetic wave:Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
Sunlight is an electromagnetic wave that gains energy as it travels through the air to reach the person.

Determine if each picture is a high or low tide.
Note: only ONE picture can be a high tide and only ONE picture can be a low tide!
Answer: the first picture is low tide
Explanation: on the first picture the boat in the center isn't in the water and on the second picture the waves are more agressive which happens with a higher tide
Answer:
The first picture with the boat is low tide. You would not park your boat so shallow so it would be low tide. The second picture with the waves is high tide. Big waves tend to bring in the high tide.

A biology teacher gives each pair of students in her class a group of 30 newly sprouted bean plants. She tells the class to design and carry out an experiment with these plants. After one month, the students compile the data shown below.
Answer: I think It's D
The conclusion that can be made from the experiment is that the difference in growth between group 1 and group 5 seedlings shows that light impacts plants' growth.
Group 1 plants were exposed to 12 hours of light per day while group 5 plants were not exposed to light at all.
At the end of the experiment, group 1 plants produced a significantly higher number of leaves (8) and grow far taller (13 cm) than group 5 plants who were only able to produce a single leaf and grew 4 cm tall.
Also, the majority of group 1 plants were alive after 30 days of the experiment while the majority of group 5 plants had died.

A mutation in which segments of a gene are removed is known as this type of mutation
Answer:
Yes, if you need any help ask :D
Explanation:
------> A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stage!!
Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence
Answer:
It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

how does the structure of DNA determine the structure of RNA?
A- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases cytosine in DNA and uracil in RNA will pair together when DNA acts as a template for constructing RNA.
B- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases uracil in DNA and guanine in RNA will pair together when DNA acts as a template for constructing RNA.
C- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases adenine in DNA and thymine in RNA will pair together when DNA acts as a template for constructing RNA
D- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA
The nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).
During transcription, a sequence of DNA is used as template to create an RNA, usually an mRNA.In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Guanine, Thymine, Cytosine and Adenine.According to the base pair rules, Adenine pairs with Thymine (Uracil in RNA), whereas Guanine pairs with Cytosine.In conclusion, the nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).
