Write down only the correct name next to the relevant question number.
1.1 A protozoan which moves using its pseudopodia.
1.2 A protozoan which moves using its flagellum.
1.3 A filamentous green alga.
1.4 A unicellular green alga.
1.5 Microscopic protists which appear as symmetrical, human-made, and
glass-like ornaments.
1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.

1: What gases are used and expelled by photosynthesis and respiration?
2: Where are the largest concentration of ozone and what value does it have?
3: What happens to the surface of the earth when there is an increase in greenhouse gases?
Answer:
1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration
2. stratosphere where ~90% of it is
3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth
Explanation:
Answer:
1. Used by Photosynthesis: CO2 Expelled: O2
Used by Cellular respiration: O2 Expelled CO2
2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”
3. The surface of the earth heats up

Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil
The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
What are nitrogenous base?
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.
The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body. High-density lipoprotein can lower your risk for heart disease and stroke.
Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

Help please answer fast!!!
Answer:
A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.
So there are a lot of things that can impact on how we see the graph of the same data.
About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.

White tailed deer begin their reproductive cycle in the fall. Rising testosterone levels in
male white tailed deer cause them to start their breeding season around the same
time. Offspring are born the following spring and summer.
What is the most likely explanation for the white-tailed deer having a seasonal
breeding cycle instead of a monthly breeding cycle?
The explanation for the white-tailed deer having a seasonal breeding cycle should be that deer provide birth in the spring and summer.
What is seasonal breeding?It is considered to be animal species so it should be successfully mated at the time of specific times of the year. It permits the optimization of survival of young because of factors like food, water availability, etc
So, here deer provide birth in the spring and summer for avoiding the pregnancy at the time of hot summer months.
