Besides poaching, what other major factor is causing a decline in elephant populations?

Answers

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.

Match each tool with its influence on science

Answers

Answer:

xray - allows scientists to see dense structures

Microscope - view things that cannot be seen with the naked eye

Telescope - stars, planets and black holes

Ultrasound - see inside the body in real time

Explanation:

Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.

Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.

Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.

Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.

X-rays enable researchers to observe dense formations. View objects using a microscope that is invisible to the eye. Telescope: black holes, planets, and stars see into the body in real-time using ultrasound.

What is the tool microscope's influence on science?

X-rays depict the body's dense internal architecture (bones). But it's not in real-time,  typically, pictures are taken and then looked at afterward.

The name of the instrument, "microscope," gives it away—think small! as a result, not visible to the eye. The word "telescope" refers to anything far out or remote in its first half.

When a baby is still developing, their health is monitored using ultrasound technology.

Therefore, view objects using a microscope that is invisible to the eye.

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.

Answers

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.

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 hormone

Osteoclast 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 hormone

The 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.
