Does the plant cell or animal cell have a larger vacuole?
Answer:
Plant cell
Explanation:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright.

Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait
are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes
Answer:
The answer is B) alleles
Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
What do you mean by traits?Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.
Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.
Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

Energy is transferred into the ecosystem when
1.when bacteria absorbs nitrogen from other organisms
2. dead organisms decay and form organic matter
3. rodent prey on invertebrates
4.plants grow from the soil
Answer:
2
Explanation:
Energy is transferred between organisms in food webs from producers to consumers.
The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Answer: between organisms in food webs from producers to consumers.

Animal cells must work together in order to obtain nutrients and produce energy. Students were asked to create an explanation about the organelles involved in this process. Which student’s explanation is correct?
A. Student D is correct because they said the cell membrane allows the nutrients into the cell and the cytoplasm allows the nutrients to move across to the cell to be broken down by the mitochondria to create energy, and the lysosome gets rid of waste.
B. Student A is correct because they said the nucleus provides the organelles instructions to carry out their jobs, the lysosome breaks down the nutrients to create energy, and the mitochondria gets rid of waste.
C. Student B is correct because they said the nucleus provides the organelles instructions to carry out their jobs, the cell membrane stores the nutrients until the mitochondria breaks them down to create energy.
D. Student C is correct because they said the cell membrane allows the nutrients into the cell and the cytoplasm allows nutrients to move across to the cell to be stored in the lysosome until they need to be broken down by the mitochondria.

Subject: Nitrogen cycle
Answer: Free nitrogen comes from bacteria breaking down the nitrogen compounds which causes it to be released in the air. Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!
Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

There is a relationship between breathing and cellular respiration. Breathing involves taking in oxygen and releasing carbon dioxide. How does the oxygen affect the process of cellular respiration?
> Oxygen and ATP combine to produce energy in the form of carbon dioxide.
> Oxygen and glucose combine to produce energy in the form of ATP molecules.
> Oxygen and hydrogen combine to produce energy in the form of ATP molecules.
> Oxygen and carbon dioxide combine to produce energy in the form of ATP molecules.
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. ...
