Select all of the arrows in the model that represent the movement of nitrogen from an abiotic system to a biotic system.
Answer:
Nitrogen compounds in the soil ---> Plants
Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)
Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)
Explanation:
This model in the image section is portraying the nitrogen cycle, which involves the transfer of nitrogen within biosphere, atmosphere, and lithosphere etc. The abiotic components of this model are the non-living parts while the biotic components are the living parts.
In this model, the movement of nitrogen from abiotic or non-living component of an ecosystem to the biotic or living component is as follows:
Nitrogen compounds in the soil ---> Plants
Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)
Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)
a student needs to find the density of a cube. each side of the cube measures 3 cm and the mass of the cube is 12g. what is the approximate density of the cube?
A. 0.4g/cm3
B. 2.25g/cm3
C. 4.0g/cm3
D. 36g/cm3
Answer:
Density = 0.4g/cm³
Explanation:
Given
Mass = 12 g
Length = 3 cm
Required
Determine the density.
To calculate density, we need volume.
Volume of a cube is:
Volume = Length ³
Hence:
Volume = (3cm)³
Volume = 27cm³
Density = Mass/Volume
Density = 12/27
Density = 0.4g/cm³ --- Approximated
Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves.
The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. What is the term for a group of similar cells working together?
Question 11 options:

The skin cells of a scorpion organize together to form a hard covering called a carapace, which helps protect the scorpion. "Tissue" is the term for a group of similar cells working together. The last option is the correct answer.
What is a tissue?In a single-celled organism, cells perform all of the body's functions, whereas in multicellular animals, cells join together to form tissue, tissue joins together to form organs, and organs join together to form organ systems, and all functions are divided. By the time zygote formation occurs, there is only one cell present, and that cell has been divided, specialized, and assigned specific functions.
Some cells make stem cells, some make epithelial cells, and so on. The tissue is a group of cells having a similar function, such as epithelial tissue, which has many cells but all of them perform the same function, that of a skin cell; all of them have sweat glands, etc.
Hence, "tissue" is the term for a group of similar cells working together. The last option is the correct answer.

Complete the Concept Map to compare the locations and remodeling functions of osteoblasts and osteoclasts, and explain how hormones and physical stress regulate bone remodeling.
Answer:
The correct answer is attached as an image.
Explanation:
Bone remodeling occurs by the remodeling units osteoblast which is bone deposition and osteoclast which is Bone resorption.
Bone deposition is the process that involves the deposition of minerals in bone tissues which takes place due to the process of osteoblast mainly. the bone deposition is possible in three ways when
- there is an increase in blood calcium.
- there is an increase in mechanical stress.
- decrease in parathyroid hormone
Osteoclast cause the degrade of bone tissue by releasing calcium ion from bone tissue which required opposite conditions than osteoblast that are -
- there is a decrease in blood calcium.
- there is a decrease in mechanical stress.
- increase in parathyroid hormone
A decrease in blood Ca++ concentration causes the parathyroid gland to release PTH, PTH results in osteoclasts to degrade bone tissue which releases Ca++ into the blood. A high level of Ca++, calcitonin results in calcium deposition into the bone.

Bone remodeling involves osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.
What is bone remodelling?Bone remodeling involves the processes by which the bone tissue is remodelled by the action of the osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.
Bone deposition is the process by which bone tissues ate mineralized by means of the osteoblast.
Bone deposition occurs through three possible ways:
increase in blood calcium.increase in mechanical stress, and decrease in parathyroid hormoneOsteoclast are involved in the degradation of bone tissue producing opposing effects to that of the osteoblast as follows:
decrease in blood calcium.decrease in mechanical stress, andincrease in parathyroid hormoneThe parathyroid gland releases PTH in response to low bllod calcium.
PTH induces osteoclasts to degrade bone tissue which releases calcium ions into the blood.
The increase in blood level of calcium ions induces calcitonin to increase calcium deposition in the bones.

What are comets? How are they formed? Write a paragraph about them.
Comets are small bodies that go around/orbit the sun. A comet can also pack more damaging force than even an asteroid of the same mass. The dusty particles combined with ice and water, become the amazing beginning of a Comet.

Besides poaching, what other major factor is causing a decline in elephant populations?
Answer:Habitat Loss and conflict with communities
Explanation: Habitat loss and conflict with communities
Most elephant habitat still extends outside protected areas, and the rapid growth of human populations and the extension of agriculture into rangelands and forests formerly considered unsuitable for farming mean that elephant habitat is continuing to be lost.
Increasing conflict with people
As human populations expand, more land is being converted to agriculture. So elephant habitat is shrinking and becoming more fragmented, and people and elephants are increasingly coming into contact - and conflict - with each other.
Elephants sometimes raid farmers’ fields and damage their crops – affecting the farmers’ livelihoods – and may even kill people. Elephants are sometimes killed in retaliation.
With human populations continuing to grow across their range, habitat loss and degradation - and conflict with communities - will remain major threats to elephants' survival.
Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.
What are the reason behind the decline of the population of elephants?The reason behind the decline of the population of elephants are poaching, besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.The logistics growth curve has been defined as the population per capita growth rate is decreases and get smaller and the size of population increases maximum applied by resources which are limited in the environment which is known as the K that has been carrying capacity.
The logistics population growth has been represented by the logistic growth curve on a line graph and the shape of the curve has S - shaped that represents the slow increase, and rapid growth in the population and after that there has been reduction in the growth.
The best example of the logistics growth has observed in the wild population that includes the sheep as well as harbor seals. In both of the cases the number of the population has been increases and carrying capacity for small period of time.
Therefore, Besides poaching other major factor is causing a decline in elephant populations is habitat Loss and conflict with communities.
