Healthy rain forest ecosystems provide ecosystem services, such as clean air, shade, food, and water. How might an increase in palm oil plantations affect humans who live nearby?

Answers

Answer:

Negatively affected.

Explanation:

Increase in palm oil plantations negatively affected humans who live in nearby area because this palm oil plantations is the cause of deforestation. Due to this palm oil plantations, deforestation occurs that leads to loss of habitat of many species as well as decrease in the area of forest which provides us clean air, shade, food, and water. The decrease in forest area also causes natural disaster such as floods in the region. Forests play a significant role in the prevention of floods in the region.

trees, they grow (slow/ast) and die (young/old),
slow, old

Slow young
Fast young

Answers

Answer: They grow slow and die old

Explanation: I just took a  test with the same question and it said I was correct plus it is on this website https://untamedscience.com/biology/biomes/coniferous-forest-biome/

Coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.

What are the characteristics of Coniferous trees?

The characteristics of Coniferous trees are as follows:

They have leaves that are very thin in the shape of needles. These trees don't have flowers but produce cones. Due to this, they are called coniferous trees.These trees grow in areas that have snowfall. Hence these trees have needle-like leaves that do not allow the snow to rest on them.

The approach and properties of coniferous trees are absolutely opposite to those of deciduous trees. This is because the environment of both conditions differs greatly.

When there are not enough nutrients present in the soil, coniferous trees generally flourish because they take the opposite approach with respect to deciduous trees. Due to this, they grow slowly and die old.

Therefore, coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?

Answers

Hi, rachellelunaa!!

I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.

I really hope this answers your question!!

The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.

What are the cranial bones?

Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).

The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.

Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.

Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Which molecule regulates how the organism looks and acts?

Answers

Answer:

In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.

Explanation:

Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.

What is gene regulation?

Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.

Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.

Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.

Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.

Part 1: Comprehension Questions
1. What are two things mentioned in the reading that can happen that might affect an ecosystem?
2. Define ecological succession.
3. What is primary succession?
4. Describe an example of primary succession.
5. What is a pioneer species?
6. How long might it take for an ecosystem to become balanced?
7. What happens when an ecosystem is in equilibrium?
8. Define climax community.
9. Name two things that can disrupt a community.
10. What is secondary succession?

Answers

Answer: 1.  One community replacing another as a result of changing abiotic and biotic factors. Establishment of a community in an area of bare rock that does not have topsoil. Lava flow destroys an ecosystem and hardens into bare rock. 2. Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. 3.Primary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals first colonize a barren, lifeless habitat. 4.   Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed. 5. Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. 6. THIRTY TO ONE HUNDRED YEARS . 7. Ecological balance has been defined by various online dictionaries as "a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession." and "A stable balance in the numbers of each species . A healthy ecosystem is said to be in equilibrium, which is a relatively stable state that keeps population sizes within a sustainable range (not too many of a certain species alive or dead). ... Some bears will starve and fewer cubs will be able to prosper, leading to a smaller overall population the next year. 8.A climax community is the last stage in succession, a stage where an ecosystem reaches a stable state. It is a mature ecosystem. ... Climax communities are stable. 9.  Disturbances such as fire or flood can disrupt a community. After a disturbance, new species of plants and animals might occupy the habitat. Over time, the species belonging to the climax community are likely to return.  10. Secondary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or road or building construction)— ... brainliest? plzz

Attempting to answer this question, a researcher tested a random sample of 48 mice and observed which forepaw (right or left) the mice used to retrieve food from a narrow tube. Eighteen of the mice used their right paw, while the rest used their left paw.Does this data suggest that mice show a preference towards one paw over the other? Carry out the appropriate test and include all steps for full credit.
