Answer 2

Diagram 4 best illustrate an event in reproduction that would most directly lead to the formation of a human embryo.

How human embryo formation  occurs?

During fertilization, the sperm and egg unite in one of the fallopian tube of female reproductive system to form zygote.

Then zygote goes through some stages of embryogenesis in order tp reach implantation step.

Here in the diagram 4 sperm and egg are shown to get unite and formation of zygote can take place which eventually lead to embryo formation.

How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

What is the main way that fossil fuel use impacts the environment?

A) invasive species

B) water use

C) global climate change

D) soil degradation​

Answers

Answer:

C. Global Climate Change

Explanation:

When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.

Global climate change is the main way that fossil fuel use impacts the environment. Therefore, option (C) is correct.

Why fossil fuels impact environment?

Fossil fuels such as coal, oil, and natural gas are formed over millions of years from the remains of dead plants and animals. When these fuels are burned to produce energy, they release large amounts of carbon dioxide and other greenhouse gases into the atmosphere.

These gases trap heat from the sun and cause the Earth's temperature to rise, leading to climate change and other environmental impacts. In addition to greenhouse gas emissions, fossil fuel extraction, transportation, and processing can also have other negative impacts on the environment, including air and water pollution, habitat destruction, and oil spills.

Fossil fuel use also contributes to the depletion of finite resources and the loss of biodiversity. As a result, there has been increasing emphasis on transitioning to renewable energy sources to mitigate the negative impacts of fossil fuels on the environment.

WHAT IS MUTUALISM?

Mutualism is the type of association between two organisms in which both parties benefit from one another.

An example of mutualism is the relationship between bacteria and leguminous plants.

Leguminous plants provide shelter for the bacteria while bacteria help the plant to fix atmospheric nitrogen.

how does the structure of the leaf allow it fulfil the requirements for gas exchange surface?
(pls don't put it in a file or pls no link) :)​

Answers

Explanation:

The structure of the leaf is adapted for gas exchange. The cells in the spongy mesophyll (lower layer) are loosely packed, and covered by a thin film of water. There are tiny pores, called stomata , in the surface of the leaf. Most of these are in the lower epidermis, away from the brightest sunlight.

The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.

In the light, the guard cells absorb water by osmosis, become turgid and the stoma opens.

In the dark, the guard cells lose water, become flaccid and the stoma closes.

Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open.

The Grasshopper population will decrease if population of grasshopper dies off.

What is Chemical spray?

population ecology and making predictions about population dynamics would be sufficiently challenging based only on the complicating qualities that living entities bring to the problem (variation and history), but an ecologist must also taken into consideration the particularities of a given system.

Grasshoppers cause serious economic damage to both crops and rangeland, although the greatest concern has been with respect to losses of livestock forage in the latter system (Hewitt and Onsager 1983, Joern and Gaines 1990).

What is lacking, however, is any substantive advance with regard to state and federal forecasting of rangeland grasshopper population dynamics that would allow limited resources to be acquired, allocated, and applied in an optimal manner.

Therefore, The Grasshopper population will decrease if population of grasshopper dies off.

What were these groups called? WILL GIVE 90 POINTS AND BRAINIEST PLEASE HELP Read the speech "Voluntourism: An Opportunity Too Good to be True" and consider the advertisement "The Opportunity of a Lifetime." Then, answer the question. Voluntourism: An Opportunity Too Good to be True A Speech to the Student Body of Evergreen High [1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference. [2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help." [3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved. [4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels). [5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour. [6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.
