Which of the following is NOT one of the major land biomes? a. tropical rain forest c. temperate grasslands b. temperate savanna d. temperate deciduous forest
Answer:
Temperate Savanna.
Explanation:
Savanna is not temperate, it is also called tropical grasslands, further supporting my answer. It is PART of the kinds of grasslands, So because it is a part, it is not a major Biome.
Temperate savanna is not the major land biomes.
What is Biomes?Some of the electrons in metallic atoms are held there quite loosely. As a result, they frequently lose electrons and generate cations. In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
As a result, when two atoms from a metallic and a nonmetallic element unite, the nonmetallic atoms usually tend to take one or more electrons from the metallic atoms and create ions.
One-third of the Earth is covered in forests, which are primarily made up of trees. A large portion of the terrestrial biodiversity of the planet, including insects, birds, and mammals, is found in forests.
Therefore, Temperate savanna is not the major land biomes.

Answer:
d
Explanation:
The following table shows the currently accepted half-life values for four parent isotopes.
Parent Isotope Currently Accepted Half-Life Values
Uranium-238 4.5 billion years
Uranium-235 704 million years
Thorium-232 14.0 billion years
Rubidium-87 48.8 billion years
Potassium-40 1.25 billion years
Samarium-147 106 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope?
Rubidium-87
Thorium-232
Uranium-235
Uranium-238
Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.
ok the answers are simple:
Parent Isotope Currently Accepted Half-Life Values: is the first one uranium-238 4.5 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope: uranium- 238

1) How do meteorologists know one storm from another especially if two are occurring at once?
2) If the current storm starts with an ‘H’ what are the next five storms for this year?
Answer:
Satellites, Radars, Storm Spotters
Explanation:
Satellites: Satellites take pictures of Earth at regular intervals from space, telling us where clouds are located. Meteorologists watch these pictures over time to watch for rapidly growing clouds, a clue to a possible thunderstorm. Satellites also can tell us the temperature of the cloudsRadars: Radars send out electromagnetic waves that can be reflected back by precipitation or other objects in the air. Radars can measure the intensity, size, shape, and movement of rain, hail, or debris in a storm. Radars can also show the wind speed and direction near and inside the storm, which can indicate rotation or shear.Storm spotters: Storm spotters are trained volunteers who observe and report severe weather conditions from the ground. Storm spotters can provide valuable information about the location, structure, and behavior of a storm that may not be visible on radar or satellite. Storm spotters can also confirm if a tornado is on the ground or if there is any damageMeteorologists use these tools and techniques to distinguish one storm from another based on their location, size, shape, intensity, movement, and features. They can also compare different sources of information to verify or correct their analysis of a storm.
What does the Mitochondria do to produce a ton of energy
Answer:
Mitochondria use oxygen in the cell to convert chemical energy from the cell's food into energy that can be used by the host cell.
Explanation:
hope this helps :)
Answer:
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. ... NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.

"Gametes are haploid cells." What does this sentence mean?
The sentence “gametes are haploid cells” means that gametes/sex cells have a single set of unpaired chromosomes
“Gametes are haploid cells.” This sentence means that gametes contain half the total number of chromosomes that are present in the other cells of the organism.
What are gametes?Gametes are the reproductive cells of an organism that are involved in sexual reproduction. They are specialized cells that are produced with the process of meiosis.
In animals, the male gamete is called sperm while the female gamete is called ovum or egg. Sperm is typically a smaller and motile gamete which fertilizes the egg to form a diploid zygote (2n) by the process called fertilization.
Gametes are important for sexual reproduction and the maintenance of genetic diversity in populations. They are also the key to the process of evolution, which can lead to genetic variations that can be passed on to the future generations.

Turkey vultures eat carrion, which is decaying animal matter, like roadkill. How are they classified?(1 point)
autotroph
herbivore
carnivore
omnivore
Our ecosystems' health is significantly influenced by turkey vultures. They act as nature's cleanup crews by getting rid of decaying, corpses. Thus, option C is correct.
What is the importance of vultures in an ecosystem?Vultures perform a crucial role in maintaining the balance of our ecosystems. Without them, carcasses would build up and rotting flesh would cause diseases to spread.
Which prevents the spread of certain diseases and makes the air smell much nicer overall.
Since their incredibly potent stomach acids destroy many of the poisonous substances found in dead animals, they ingest carrion quickly before it decomposes.
Given that they primarily eat dead animal corpses, vultures are excellent at cleaning out illnesses and toxins from the environment.
Therefore, Turkey vultures are carnivores which feed upon decaying animal matter.

Is due todaaay pls i need help
Answer:
Haven't done this in a while but here goes: Top left FF - Top right Ff - Bottom left fF ( or Ff?)- bottom right ff.
Explanation:
Freckles are dominant trait so Capitalized letter F ( i chose "F" because the question told me to choose a random letter to use in this problem). Yet, one son doesn't have them so there must be a presence of a recessive allele (hence, little f). This all means that both parents have one dominant allele and one recessive allele. Each one has "Ff". So then you fill it in. The first gamette of each is "F" so when the box asks for Gamette 1 you put an F and when it asks for a gamette 2 you put in a "f". Now the bottom right might be "Ff" just because you would follow the traditional order of putting the dominant allele first but, I wasn't sure. Hence the "Ff/fF" I put. That itslef wouldn't be the final answer but two options of what I believe it would be. You might know which to choose as you've seen it in class but yeah.
Here again, I haven't done this in a REALLY long time so take this with a literal grain of salt and if it doesn't line up with what you've learned in class, please disregard this response!

1. is the first blank increases or decreases?
2. Is the second blank increases or decreases?
As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
what is star luminosity ?luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.
