Answer:
- The ovary is the female organ that produces the female gametes
- The oviducts are tubes that extend from the ovaries to the uterus
- The uterus is an organ that acts to nourish and house a fertilized egg until the fetus is delivered
- Materials are supplied by the mother's placenta
Explanation:
The ovaries are the female gonads that function to produce and release female gametes (i.e., oocytes) into the reproductive tract. These organs are also in charge of producing female hormones (e.g. progesterone). The oviducts, also known as fallopian tubes, are a pair of tubes that extend from each ovary to the top of the uterus. The uterus is a thick muscular organ of the female reproductive system that nourishes and houses the embryo and fetus. Finally, materials such as oxygen and nutrients pass from the mother's bloodstream through the placenta which is connected to the fetus by the umbilical cord.

A cladogram is shown below. What is a derived characteristic that distinguishes the salamander from the perch? lungs claws or nails fur jaws
About the question:
You will a cladogram in the attached files.
Answer:
lungs
Explanation:
A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.
• The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
• The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.
• The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.
So the cladogram represents the relationship between groups according to a derived character.
The derived character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
In the attached cladogram, you can see that the lungs are the derived character that distinguishes the salamander from the perch.
Claws or nails separate salamander from lizards.
Fur separates birds and reptiles from mammals.
Jaws separate hagfish from perch.
Mutations occurred in evolution producing new traits, and these traits also appear in posterior groups. So, after the hagfishes emerged the jaws, and all the animals that followed the hagfishes have jaws.
Lungs appeared after the perch and before salamander, so salamander, and all the posterior animals, have lungs. And so on.

Some people worry that the increasing number of cell phones will cause cancer
because of the energy of the radio waves they emit. Cell phones are a new technology
that only recently became widely used. And because cancer takes years to develop, the
amount of risk is not yet known.
K
Research this issue, and summarize what's known so far. In your summary, include
information about the energy of radio waves. Be sure to only use credible sources.
Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer:
No.
Explanation:
No, the increasing number of cell phones will not the cause of cancer because it emits low intensity of radio waves. Radiations such as x-rays, gamma rays, alpha particles, beta particles, and neutrons are responsible for causing damage to the cell and the main cause of cancer. High intensity of radio waves heats up the cells not causing cancer disease so we can conclude that the increasing number of cell phones will not cause cancer disease in humans.

For this assignment, you will ask questions about the factors that have caused a rise in global
temperatures over the past century. Then, you will conduct research to answer your questions. You will
also graph provided information, analyze the graphs, and make conclusions based on the graphs. Finally,
you will write a paper describing the conclusions of your research and graphs.
Background Information
Global temperature change is a gradual increase in the overall temperature of the Earth's atmosphere.
Both human activity and natural processes have contributed to this temperature increase. Examples of
human activities include the burning of fossil fuels, cement production, and agricultural activity. Examples
of natural processes include changes in incoming solar radiation and volcanic activity.
Scientists present evidence for the rise in global temperature in the form of tables, graphs, maps, and
models. For example, scientists build climate models (computer simulations of climate systems) to
explore the causes and effects of global temperature change and to predict future trends. These models
predict that the Earth’s average surface temperature will rise as greenhouse gas concentrations continue
to rise. Based on these models, scientists predict that average surface temperatures could rise by
between 2°C and 6°C by the end of the 21st century.

For the global population growth rate to reach zero, the number of births would have to be
Answer:
same as the number of death
... is what you fill in.
Explanation:
If the death and birth number are equal, there are no changes in numbers made.
For the global population growth rate to reach zero, the number of births would have to be same as the number of death.
What do you mean by population growth rate?Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.
Population in the world is, as of 2022, growing at a rate of around 0.84% per year (down from 1.05% in 2020, 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current population increase is estimated at 67 million people per year.
The world's population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050 and could peak at nearly 10.4 billion in the mid-2080s.

it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.

-1.0
Answer:
-0.50
Explanation:
For the graph displayed, the most probable value of the correlation Coefficient is - 0.50 ; the line of best fit has a negative skoe and hence will have a negative relationship as the correlation Coefficient is a statistical value which measures the degree of relationship between two variables. Also, the distribution of data in the plot does not give a perfect fit, hence a correlation Coefficient of - 1.0 isn't possible for the distribution shown.

Scientists sink concrete blocks in oceans to create artificial coral reefs. Which successive event most likely occurs first on this type of coral reef
Answer:P
Explanation:got it right
Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.
What is Coral reef?Coral reefs are significant ocean habitats that make a strong argument for the dangers of climate change. Reefs are a significant contributor to the biodiversity of the planet; they have been referred to as "the rain forests of the seas." One of the most diverse environments on earth, coral reefs are home to 25 percent of all marine species, according to scientists.
According to Paulo Maurin, coordinator of education and fellowships for NOAA's Coral Reef Conservation Program, the reefs are essential to the biodiversity of our world.
Many fish species use them as fruitful nurseries, giving the young fish a place to live and an opportunity to develop, according to him. "The diversity of coral reefs is so great that we don't have a firm count of all the species that live there,"
Therefore, Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.
