Which best describes what is occurring in this population of squirrels? Number of Squirrels Entering and Leaving a Population after 1 Year Cause of change Number of squirrels Died from predation 2 Born 4 Immigration 10 Left to find food 3 Died from disease 8 Left to find a mate 3
Answer:
Explanation:
The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.
Looking at the data generated,
Died from predation =2
Born=4
Immigration=10
Left to find food =3
Died from disease=8
Left to find mate=3
If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.
Answer:
A
Explanation:
Population growth is decreasing.

Describe the application of mitosis in agriculture and food technology with example.
please help me
Answer:
Explanation:
Mitosis is a form of cell division that takes place in the nucleus, it involves series of steps from prophase to metaphas to anaphase and Telophase. It results in the formation of two daughter cell that are genetically identical with the parent having the same number of chromosome.
Mitosis helps in the formation of new cells, it replaces the old cells with new one. Living things are made up of cells including plants and this cells when worn out are been replace through mitosis division to aid good growth pattern.
Mitosis helps in producing the exact copy of cell from the parent leading to genetically identical offspring having the important features, traits as the parents that can be useful in agriculture.
A actively dividing cells aids growth, water melon is a fruits its growth is aid by mitosis.
Each cells has Identical DNA(Deoxyribonucleic acid) with chromosome located in them.
This chromosome can be doubled to get polyploid.
Polyploid have led us to existence of new varieties of crops such as the seedless water melon, wheat.

How do atmospheric conditions influence weather patterns?
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather. hope this helps you :)

Which substance would most likely form sedimentary rock?
O cooled lava
melted rock
changed igneous rock
small pebbles
Answer:
small pebbles
Explanation:
Small pebbles would most likely form sedimentary rock.
What are sedimentary rocks?Sedimentary rocks are formed from the accumulation and cementation of small rock particles or sediments such as sand, silt, and clay, as well as other materials like shells, organic matter, and minerals that have been weathered and eroded from pre-existing rocks.
Over time, these sediments are compacted and cemented together to form solid rock. Therefore, small pebbles are more likely to be transported by wind or water and deposited as sediment, eventually forming sedimentary rocks through compaction and cementation. Cooled lava, melted rock, and changed igneous rock are more likely to form igneous rocks through solidification or crystallization.

You notice two birds living in different parts of the same tree outside your house. They have similar markings and are of a similar size. After continual observation, you realize that they cannot interbreed. Do these birds belong to the same population? Why or why not.
Answer:
They do not belong to the same population
Explanation:
These two similar birds do not belong to the same population because a population is made up of groups of similar organisms of the same species that occupy the same geographical region including the capability to interbreed. This two birds despite the similar markings, they do not have the capability to interbreed thus they are not of the same population.
Answer:
The correct answer is "The two birds do not belong to the same population because they cannot interbreed".
Explanation:
A population is defined as a group of individuals of the same species living in the same are at the same time and with the capability of interbreeding. In this case the two birds share the same area and time, but they are not able to interbreed. Excluding the possibility that the two birds are of the same sex, we can speculate that the two birds are of the different species even though they look very similar. Therefore, we can conclude that the two birds do not belong to the same population.

La circulación __________ lleva la sangre a los pulmones para purificarla y luego la regresa al corazón para que la circulación __________ se encargue de repartirla a todos los órganos del cuerpo11.La parte líquida de la sangre se llama __________
Answer:
pulmonar; sistemica; plasma
Explanation:
La circulación pulmonar es responsable de llevar sangre del corazón a los pulmones. En este caso, la sangre rica en dióxido de carbono sale del ventrículo derecho a través de la arteria pulmonar, llega a los pulmones, sufre intercambio de gases y regresa a la aurícula izquierda del corazón a través de las venas pulmonares.
La circulación sistémica es responsable de garantizar que la sangre oxigenada se transporte por todo el cuerpo y que la sangre rica en dióxido de carbono regrese al corazón.
El plasma sanguíneo es una solución acuosa amarillenta que consiste en agua, minerales y proteínas. Su función es transportar estas sustancias por todo el cuerpo. El plasma representa aproximadamente el 55% del volumen sanguíneo.

Which effect does a gradual decrease in pH from 13 to 1 have on the action of amylase?
pH can be described as a measure that is used to depict the acidity and alkalinity of a solution usually on a logarithm scale. Some enzymes in the body functions with pH (Hydrogen concentration).
The effect of pH with a gradual decrease from 13 to 1 on the action of amylase would cause amylase to not function and the enzyme to become denatured.
Some particular enzymes need specific hydrogen concentration (pH) to work. The pH scale measures this with 7 being neutral. Concentration lower than 7 becomes acidic going down to 1 and those higher than 7 becomes more alkaline going up to 14.
Amylase needs a pH range from 6 to 7 to function properly in the stomach but as the pH concentration becomes lower going to 1, the surrounding turns acidic causing the enzyme to become denatured and not function.

Select two specific components of the cell membrane and explain how each affects the permeability of the cell membrane. Meaning, what specific materials are regulated by the given component and how
Answer:
Phospholipid bilayer and carbohydrates.
Explanation:
Phospholipids form a double layer that protects the cell from the outside, in this layer the heads of the phospholipids, which are hydrophilic, are orientated towards the inside and the outside of the cell, and the tails of the two layers, which are hydrophobic, are in contact with each other. This bilayer allows the passage of certain substances due to its polarity, the elements that are too big, are ions, or that are hydrophilic have especial channels made of proteins that allow the passage of these kinds of elements
The other component that can affect the permeability is carbohydrates. These, when they attach to lipids and proteins, form a layer around the cell that allows the passage of certain substances, allows the recognition of the cells that are from the body, and the ones that are foreign so that there can be communication between cells.
