Is Earths global mean temperature changing? explain your answer the words TREND and FLUCTUATION.
Answer:
Yes the Earths golbal mean temperature is changing.
Explanation:
The global temperature record represents an average over the entire surface of the planet. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable cyclical events (night and day, summer and winter) and hard-to-predict wind and precipitation patterns. The strong warming trend of the past four decades likely reflects a shift from comparable aerosol and greenhouse gas effects to a predominance of greenhouse gases, as aerosols were curbed by pollution controls, according to former GISS director Jim Hansen.

Identify the point where the common ancestor of the fly and spider would be located.
Answer:
The common ancestor of the fly and spider would be located in the closest where B and C converge.
Explanation:
In phylogenetic trees, two species are more related if they have a recent common ancestor. On the other hand, two species will be less related if their common ancestor is not a recent one and is located far away in the tree.
In the phylogenetic tree, the taxonomic groups of interest are located in the extremes of the lines called branches. In the present example, the fly and the spider are the species located in the extreme of the branches. The ramification point, which is also called "node" or divergence point, represents the location of the most recent common ancestor.
In the example, the point where the branches B and C get united, is the place where their common ancestor is located.
The red point in the attached file "tree1" shows you where it is located the common ancestor of the two species.

Will mark brainliest for the most answer!!! This is all easy photosynthesis y8 work pls help!! Do as much as u like but plz do help
Answer:
Roots act like straws absorbing water and minerals from the soil. Tiny root hairs stick out of the root, helping in the absorption. Roots help to anchor the plant in the soil so it does not fall over. Roots also store extra food for future use.
The various functions of water in plants include: maintaining cell turgidity for structure and growth; transporting nutrients and organic compounds throughout the plant; comprising much of the living protoplasm in the cells; serving as a raw material for various chemical processes, including photosynthesis;
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
A plant has two organ systems: 1) the shoot system, and 2) the root system. The shoot system is above ground and includes the organs such as leaves, buds, stems, flowers (if the plant has any), and fruits (if the plant has any).
Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf, stem, root, and reproductive structures. The first three are sometimes called the vegetative organs and are the subject of exploration in this chapter.
Roots keep a plant in the ground. They also take in water and nutrients from the soil.
Leaves absorb sunlight, and make food for the plant by photosynthesis. ...
The stem supports the leaves and flowers. ...
Reproductive organs allow a plant to produce new plants.
Explanation:
As the trait is dominant and controlled by a single gene, the mutation must have occurred on both diploid copies, true or false?? with reason please
Answer:
True.
Explanation:
Diploid copies are cells generated as copies of other cells and which have two homologous copies, exactly the same, of the cell that gave rise to it (the mother cell). In this case, if the mother cell has a mutation that causes a dominant characteristic and controlled by a single gene, it means that its diploid copies will have that same mutation, since they are exact copies.
Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides everytime suzanne gets the carrier out. Which beat describes the cats behavior?
Answer:
C. Conditioned
Explanation:
Based on the reaction that the cat is having it seems that the cat has a conditioned response to the carrier being out. This means that the cat has a learned response that is directly associated with a certain stimuli which in this case is the carrier. Since he has a bad experience with the carrier before, he now reacts in a scared manner every time he sees it.
Answer:
C. conditioned
Explanation:
A gene may be described as
Answer:
The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.
Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.
Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.
The protein thus formed corresponds to a particular trait ( like eye color, hair color).

scientific concept for the water cycle
Answer:
Evaporation, condensation, precipitation, Surface Runoff, Infiltration, transpiration
Explanation:
There are six important processes that make up the water cycle. These are:
Evaporation
Evaporation is the process where a liquid, in this case water, changes from its liquid state to a gaseous state. Liquid water becomes water vapor. Although lower air pressure helps promote evaporation, temperature is the primary factor. For example, all of the water in a pot left on a table will eventually evaporate. It may take several weeks. But, if that same pot of water is put on a stove and brought to a boiling temperature, the water will evaporate more quickly.
During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.
Condensation
Condensation is the opposite of evaporation. Condensation occurs when a gas is changed into a liquid. Condensation occurs when the temperature of the vapor decreases.
When the water droplets formed from condensation are very small, they remain suspended in the atmosphere. These millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dust particles present around which the droplet can form.
Precipitation
When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs. The raindrops fall to Earth.
As a result of evaporation, condensation and precipitation, water travels from the surface of the Earth goes into the atmosphere, and returns to Earth again.
Surface Runoff
Much of the water that returns to Earth as precipitation runs off the surface of the land, and flows down hill into streams, rivers, ponds and lakes. Small streams flow into larger streams, then into rivers, and eventually the water flows into the ocean.
Surface runoff is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs.
Infiltration
Infiltration is an important process where rain water soaks into the ground, through the soil and underlying rock layers. Some of this water ultimately returns to the surface at springs or in low spots downhill. Some of the water remains underground and is called groundwater.
As the water infiltrates through the soil and rock layers, many of the impurities in the water are filtered out. This filtering process helps clean the water.
Transpiration
One final process is important in the water cycle. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration. In large forests, an enormous amount of water will transpire through leaves.
