The presence of which of the following cell structures would tell him that
the cell is eukaryotic?
A. Nucleus
B. DNA
C. Cytoplasm
D. Ribosomes
The presence of nucleus would tell him that the cell is eukaryotic.
Eukaryotic cells are all those cells in whose cytoplasms a well-defined cell nucleus can be found, which contains most of its genetic material (DNA).
In this they differ from prokaryotic cells, which are much more primitive and whose genetic material is dispersed in the cytoplasm.
Eukaryotic cell is characterized by having within it the hereditary genetic material (DNA) of the organism and by having a complex structure composed of organelles that fulfill different essential functions in the cell.
Cell nucleus being the cell structure that contains the genetic material of the living being (DNA), and it is where the various functions of the cell are controlled and regulated and is covered by a nuclear envelope.
Therefore, we can conclude that the eukaryotic cell is one that has a defined nucleus, the cell nucleus is the cellular structure that distinguishes it from prokaryotic cells, where cellular activities are governed.

In activity c, you explored how temperature affects the concentration of dissolved oxygen in a pond use the three data points you collected for the cold Pond to determine the mean dissolved oxygen of the cold pond
Answer:
Add the three data and divided by 3.
Explanation:
Temperature has a great affects on the concentration of dissolved oxygen in a pond because temperature is responsible for the presence of high amount of dissolved oxygen in water. At low temperature such as in winter season, the amount of dissolved oxygen in water is higher while in warm temperature such as in summer season, the concentration of dissolved oxygen is lower. So for measuring the mean dissolved oxygen of the cold pond, you have to add the data and then divided by 3, you will get the average dissolved oxygen of the cold pond.

Earth's atmosphere is made up of mostly nitrogen (78%) and oxygen (21%); however, there are other gases in smaller amounts, like argon, carbon dioxide, neon, helium, hydrogen, and more. If there was an increase of carbon dioxide in the atmosphere, how would this affect temperature? A) The temperature would increase globally. B) The temperature would decrease globally. C) Temperature doesn't relate to the composition of the atmosphere; it has to do with the sun's rays. D) The temperature would not be affected since carbon dioxide is only one component in the atmosphere. HELP plssssss
Answer:
A
Explanation:
If there is an increase in the carbon dioxide concentration in the atmosphere, this will affect the temperature of the atmosphere. This will increase the temperature globally. Thus, the correct option is A.
What is Global warming?Global warming is a phenomenon in which the earth's average temperature has risen due to increased amounts of greenhouse gases. Greenhouse gases include carbon dioxide, methane and ozone which trap the incoming radiation from the sun.
Global warming has led to an increase in the global temperature. This has resulted in an increase in the melting of glaciers, which have led to an increase in the global sea level. This could have devastating effects on the coastal regions and species living in different environmental conditions.
Therefore, the correct option is A.

Lakes, rivers, or springs can form when
Answer:
A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. In most landscapes the land is not perfectly flat—it slopes downhill in some direction.
Lakes can be formed when glaciers melt, craters from meteorites or rivers.
springs when rainwater or groundwater is heated by magma underneath Earth's surface.

☆
A. Anaphase
B. Telophase
C. Metaphase
D. Prophase
The given diagram shown here is representing prophase of Mitosis. The correct option is D.
What is Prophase?Prophase is the first step of cell division in both mitosis and meiosis. When the cell enters prophase, DNA replication has already started after interphase. The key occurrences in prophase are the condensation of the chromatin reticulum and the removal of the nucleolus.
Anaphase: Sister chromatids are pulled apart towards opposite poles of the cell by spindle fibers.
Telophase: Two daughter nuclei start to form as the chromatids reach the poles, and the nuclear envelope begins to reassemble.
Metaphase: Chromosomes align at the equator of the cell, with spindle fibers attached to their centromeres.
Prophase: Chromosomes condense, the nuclear envelope breaks down, and spindle fibers start to form.
Therefore, the correct option is D.

What do paleontologists do when they uncover incomplete fossils
Answer:
Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).

Small-chain fatty acids can enter the bloodstream directly, but large-chain fatty acids must be packaged first before entering the . can be carbohydrate-, protein-, or fat-based. remove cholesterol from tissues and deliver it to the liver for use in bile or excretion. Linoleic acid and alpha-linolenic acid are considered , and must be obtained from the diet. is needed to help mix fats with watery fluids. Carriers that transport monoglycerides and fatty acids to intestinal cells are called . contains 6 to 8 fatty acids connected to sucrose, and cannot be broken down by digestive enzymes. A is a lipoprotein carrier that transports digested fat and other lipids through the lymph system.
Answer:
lymph
fat substitutes
high-density lipoproteins
essential fatty acids
emulsification (bile)
micelles
olestra
chylomicron
Explanation:
Short-chain fatty acids can be absorbed directly into the bloodstream by the intestine capillaries, while long-chain fatty acids are released into the tiny intestine. Fat substitutes are chemical compounds that have similar properties of fats and oils, with fewer calories than fat. High-density lipoproteins (HDL) are referred as "good" cholesterol because they transport cholesterol from other body parts back to the liver. The alpha-linolenic acid and linoleic acid correspond to omega-3 and omega-6 fatty acids, respectively, and they are essential fatty acids that need to be consumed in the human diet. Emulsification is a chemical process consisting of mixing two immiscible liquids to form a semistable mixture. Micelles are chemical structures formed by the agglomeration of mixed lipids and bile acids, which support the action of lipases for digesting lipids. Olestra is a fat substitute that can be used in low-calorie diets for weight control. Finally, chylomicrons are ultra low-density lipoproteins (ULDLs) composed of triglycerides, phospholipids, cholesterol and proteins. The ULDLs are produced by intestinal cells.

What contributes to water's unique properties as a universal solvent, temperature moderator, and cohesive behavior? Hydrogen is a special element that does not have neutrons. The oxygen atoms of water molecules attract electrons more than hydrogen atoms. The properties are related to the crystalline structure of liquid water. The properties are related to the high electronegativity of hydrogen atoms. i think is B
Answer:
The oxygen atoms of water molecules attract electrons more than hydrogen atoms.
Explanation:
The uniqueness of water as a chemical substance is attriuted to its unique properties. These properties include being a universal solvent, having a high specific heat (temperature moderator), cohesive and adhesive nature etc.
This wonderful properties of water is due to its POLAR nature, which is when a substance has both positively and negatively charged parts to it. This is possible because the oxygen atoms (O) of water molecules attract electrons more than hydrogen atoms (H).
This POLARITY of water molecule is responsible for the HYDROGEN BONDING between water molecules and hence, contributes to the properties of water mentioned in the question (universal solvent, temperature moderator, and cohesive behavior)
