the number of consumer can never exceed the number of producer in nature why
Answer:
The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !
When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.
What are Producers and Consumers?Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.
Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.
Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.
Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

Answer:
A tall, green plant with dominant alleles for both characteristics have a genotype TTGG and its phenotype is tall and green.
Explanation:
For a given trait, the dominant allele of the allelic pair is represented in capital letters (T and G), while the recessive allele is represented in small letters (t and g).
In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.
In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.Which of the following is found in animal cells, but not plant cells?

A sample of Carbon-14 originally contained 100 g. After three half-lives have
passed, how much Carbon-14 is left?
Answer:
After 3 half lives 12.5 g of C-14 left
Explanation:
Given data:
Mass of C-14 = 100 g
After 3 half lives mass left = ?
Solution:
At time zero = 100 g
At first half life = 100 g/2 = 50 g
At second half life = 50 g/ 2 = 25 g
At third half life = 25 g/2 = 12.5 g
Thus, after 3 half lives 12.5 g of C-14 left.

What similarities and differences do you notice among the two types of metabolic reactions (dehydration synthesis & hydrolysis)?
Answer:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.

What does oxygen do in cellular respiration?
Answer:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.
Answer:
C. Both are primary producers.(THIS IS THE CORRECT ANSWER)
Explanation:
Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.
It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements. Kelps forests are shelters for these bacteria and hence both are found near the source of energy.Hence the option B both are primary producers.

which of the following is not a difference between DNA and RNA ?
Group of answer choices
they have different phosphate groups in their backbones
They have different sugars in their backbones
DNA is a double strand and RNA is a single strand
RNA replaces thymine with uricel
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Option A is correct. DNA and RNA have the same phosphate groups in their backbones.
DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA is usually found in double strands. In DNA thymine is present.
RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.
Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.
Hence, options B, C, and D are incorrect.
Therefore, Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

hoped this helped :)
The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.
EUKARYOTES:
Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc. This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc. Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.Learn more: https://brainly.com/question/21196976?referrer=searchResults

Answer:
1. pick up any fluid that has escaped the blood vessels
2. return the escaped fluid to the heart
3. remove any foreign material from the lymph
Explanation:
Lymph vessels pick up any fluid that has escaped the blood vessels and return it to the heart. Lymph nodes remove any foreign material from the lymph (bacteria, viruses, tumors) and contain lymphocytes (WBC!!!)
Each and every fluid that had already exited the blood arteries is collected by lymphatic vessels as well as returned towards the heart. Lymph nodules filter out foreign particles from either the lymph as well as house lymphocytes.

Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.
