What could explain the curve in this population growth graph? A graph has time on the horizontal axis and population size on the vertical axis. The population size was constant for a period of time, increased rapidly, and then became constant again. an unlimited food supply a natural disaster a population crash a reduction in predators
Answer:
A reduction in predators
Explanation:
I just took the test
A reduction in predators could explain the curve in this population growth graph.
How does reduction in number of predators lead to curve?The prey species soon degrades and overruns its area since there are no predators to regulate the population and modify feeding behavior.When food becomes scarce, people grow unwell and famished, and they either flee or crash.When predator populations grow, putting more pressure on prey populations and acting as a top-down control, pushing them toward extinction. As a result, the size of prey populations is influenced by both resource availability and predation.

A. Lysosome
B. B. Vacuole

Explanation:
Cell death, also called apoptosis, is an essential part of life. As cells become old or broken, they are cleared away and destroyed. Mitochondria help decide which cells are destroyed.
what is the function of RBC
Answer:
When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.
The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.
There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.
Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

Describe Piaget’s processes of assimilation and accommodation. Use an example to illustrate the processes.
Answer: For Piaget's process of accommodation it is when you change schema to accommodate new info.
example: Once you learn about something you modify your understanding of a concept to include specific categories. For example, when a child sees a dog, it has four legs and fur. But when they see a cat they create a new schema for cats.
Answer Process of assimilation adds on to pre-existing information/experiences.
example: going back to our cat-dog example. When they develop a concept of a dog as being a four-legged thing with fur, when they see a cat they will place the cat in the same category as a dog and be like "that's a dog" to anything that fits their concept of a dog.
Which of the following best describes soil fertility?
O An inexpensive way to maintain plant health and maximize crop productivity
O The amount of nutrients available in a soil
O A measure of soil quality which stays constant throughout a growing season
O The quality or ability of a soil to provide nutrients to plants
Answer:
O the amount of nutrients available in soil
Explanation:
good answer
Measure of soil quality which stays constant throughout a growing season is best describes the soil fertility.
What do you mean by soil fertility?Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.
A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities, e.g., calcium, magnesium, sulfur, iron.
The following properties contribute to soil fertility in most situations: Sufficient soil depth for adequate root growth and water retention; Good internal drainage, allowing sufficient aeration for optimal root growth.

Specific proteins produced in a cell are directly related to the A. Number of mitochondria in the cell. B. Sequence of sugars and phosphates in the cell. C. Type of ribosomes in the cell. D. Sequence of nucleotides in the DNA of the cell.
Answer:
D. Sequence of nucleotides in the DNA of the cell.
Explanation:
Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.
Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.

Which statement explains the role of genes in the process of inheriting a specific trait? Question 8 options: Genes are changed by the environment of a living thing and these changes effect the genes of the offspring. Genes in living things come together to make chromosomes which take information from offspring to parent. Genes absorb chemicals from the blood stream and carry them throughout the body of parents and offspring. Genes which are past from both parents carry the genetic material that determines inherited traits.

Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species (species A) grows faster than the other garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates
Answer:
This question lacks options, the options are:
A) Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.
B) Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A.
C) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions.
D) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The answer is D
Explanation:
According to this question, Ruby wants to investigate whether a plant species A in her garden grows faster than other plant species (B, C and D) due to the varying height she observed in them. To do this, Ruby will need to conduct a scientific investigation by measuring the height of all the plant species she is trying to compare (A, B, C, D).
However, she must do the measurements under the same conditions i.e. controlled in order not to influence the result. In order to make a scientific explanation concerning the plant growth rates, Ruby should find journal articles that describe the growth rates of each species and make comparison with her experimental/measured height values.
