Which type of limitng affects a large population more than it effects a small population

Which one is NOT one of the properties of water?

marysya [2.9K]

Answer:

a. the frozen form is more dense than the liquid form

Explanation:

The remaining properties are exhibited by water and are described as follows.

b. the frozen form is less dense than the liquid form

1. Water freezes to form ice.

2. When ice is put in water, ice starts floating in water and is visible.

3. If the density of ice was greater than water, ice would have got sunk and go downwards in the water body.

4. Hence, ice which is frozen form of water, has less density than water.

c. water is a solvent

1. The solvency is defined as the ability of a liquid to dissolve a substance.

2. Water is called the universal solvent. This means water can dissolve almost all types of substances.

3. Water is a polar solvent. The polar water molecules have the ability to break down both ionic and covalent bonds.

d. water has a high heat capacity

1. This is defined as the amount of heat needed by 1 gram of a substance so that its temperature is changed by 1 degree centigrade. The heat can either be gained or lost for the temperature to change.

2. The heat required by 1 gram of water to either increase or decrease the temperature of water is called the heat capacity of water.

e. water has a high heat of evaporation

1. This is defined as the amount of heat needed by 1 gram of a substance so that it changes its state from liquid to gas.

2. The heat required to convert 1 gram of water into vapours is called the heat of evaporation of water.

3. 1 g of water when heated at 25 centigrade needs 580 calories of heat to convert into gas.

All the above properties of water show the importance of water for life.

Explain how paleoclimatologists (scientists that study climate change) use fossils and other records to study climate change.

marysya [2.9K]

Answer:

paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)

Explanation:

Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death ________ whereas

Aliun [14]

Answer:

time; point

Explanation:

The complete question is as follows:

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.

time; point

window; point

point; time

time; temperature

When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.

Use the following words to fill in the blanks: nucleus, base-pairing, transcription, translation, genes, cytoplasm, polypeptide

Mkey [24]

Answer:

Use the following words to fill in the blanks: nucleus, base-pairing, transcription, translation, genes, cytoplasm, polypeptide chain, structure, ribosome, proteins, protein synthesis, cytosine, adenine, uracil, tRNA, mRNA, amino acid, DNA, RNA polymerase, codon.

DNA is made up of segments called nucleotides

. Genes provide the coding to create codon

. Proteins are created through the processes of translation

and transcription

. Together these processes are known as protein synthesis

. The first step in protein synthesis is transcription, where translation

is used as the template for the creation of an mRNA strand. The enzyme, RNA Polymerase

matches up the correct bases, using base-pairing

rules. When adenine is found on the DNA strand, cytosine

will be the complementary base on the mRNA strand. When thymine is found on the DNA strand, adenine

will be the complementary base on the mRNA strand.

and guanine are the other two bases that pair with one another. Since DNA is too large to leave the nucleus of the cell, tRNA

must be created. It is smaller and able to travel outside the nucleus

of a cell. Next, mRNA leaves the nucleus, heads through the cytoplasm

towards a ribosome

where translation occurs. In the ribosome, a codon

on the mRNA strand (3 bases), connects to the anticodon on a tRNA

molecule. When the codon and anticodon connect, the amino acid

on the tRNA molecule detaches, forming a polypeptide chain

which eventually makes up the protein. Proteins are essential for life because they make up the structure

of living organisms and help organisms to function.
