Answer:
The sun
Explanation:
Only producers get energy directly, either straight from the sun or by some other means. Carnivores and other consumers get energy indirectly via the consumption of producers and animals that eat producers.

Answer:
A, D
Explanation:
Some behaviors, such as nest building in birds, are determined by the genes of an organism. These innate behaviors are inherited from parent to offspring and exhibited even if the offspring does not observe its parent performing the behavior. Nest building behavior was most likely an evolutionary advantage because birds that built nests were more likely to raise their young to maturity and thus increase their reproductive success. That is, birds that laid their eggs in nests had more offspring survive to adulthood than those that did not. Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to+
Answer:
natural selection
Explanation:
According to the evolutionary theory, natural selection can be understood as the process of differential survival and reproduction of individuals due to phenotypic differences, which may be associated with different colors, sizes, behaviors, etc. The only prerequisite is that these phenotypic differential traits must be heritable, which means that they must be passed by genes from one generation to the next. For example, in the white-throated sparrow, it has been discovered two morphs that differ in behavior due to a chromosomal inversion in sex chromosomes.

An antibiotic label says to take it for fourteen days. If we stop taking the medication after ten days, what would most likely
happen to the bacteria in our body?
A The bacteria causes the human immune system to stop producing antibodies to fight disease.
B A population of bacteria resistant to the antibiotic appears.
The strain of bacteria allows the human immune system to build up resistance.
The bacteria builds up a resistance to all types of antibiotics, turning into a "superbug".
Answer:
B
Explanation:
This actually happened to me! Since you don't fully kill off all the bacteria, they will mutate and become resistant to the medication. The 14 days ensures that the bacteria will all be killed whereas 10 days allows the stronger organisms to grow and reproduce(where they typically are immune/build an immunity)
Which statement BEST describes the cell membrane in a typical bacterial cell? The membrane...
a)has the same permeability to all substances moving in and out the cell.
b) selectively controls what enters and exits the cell.
c) is composed of two protein layers with lipids floating inside.
d) is composed of protein and carbohydrates only.
Answer:
Explanation:What’s a cell? Well, on some level, it's a bag of goo. The plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo.
Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block of all living things. And the plasma membrane and cytoplasm are actually pretty sophisticated.
The membrane is a delicate, two-layered structure of lipids and proteins, and it controls what can enter and exit the cell. Similarly, the cytoplasm of a eukaryotic cell consists not only of cytosol—a gel-like substance made up of water, ions, and macromolecules—but also of organelles and the structural proteins that make up the cytoskeleton, or "skeleton of the cell."
In this article, we’ll take a closer look at the plasma membrane and cytoplasm.
The plasma membrane
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
A phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. This energetically favorable two-layer structure, called a phospholipid bilayer, is found in many biological membranes. [Close-up of a phospholipid]
As shown below, proteins are also an important component of the plasma membrane. Some of them pass all the way through the membrane, serving as channels or signal receptors, while others are just attached at the edge. Different types of lipids, such as cholesterol, may also be found in the cell membrane and affect its fluidity.

Answer: Taste
Explanation:
B. Taste (or tongue) is the only sense that can distinguish between five different types.
What do you mean by sense?
"A sense is defined as a way that the body perceives external stimuli, or is an awareness or feeling about something. Tasting, touching, seeing and hearing are all examples of a sense."
What are the different sense organs?
We have five sense organs, namely:
Eyes (for seeing).Ears (for hearing).Nose (for smelling).Tongue (for tasting).Skin (for touching).Which sense can distinguish between five basic tastes?
"We use our tongues to distinguish between five basic tastes, i.e. sweet, sour, salty, bitter and umami."

Based on the description of DNA, given in the Do Now, what could be the nucleotide composition of a DNA double helix? 90 points 20% adenine, 20% guanine, 30% thymine, 30% cytosine 60% adenine, 20% thymine, 10% guanine, 10% cytosine 20% adenine, 20% thymine, 30% guanine, 30% cytosine 60% adenine, 20% guanine, 10% thymine, 10% cytosine
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

How long does it take for a jellyfish to reproduce
Answer:
A jellyfish might spend one year as a medusa, but it can spend several years in the polyp stage. Polyps are stationary and reproduce asexually. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower.

2. What are the four water sources, referred to as "taps," that Sedlak believes will solve our urban water crisis?
3. Sedlak closes his talk by pointing out the benefits to creating and reinventing how we obtain our water supply. Discuss some of those benefits and explain how they relate to what you learned in the unit.
Answer:
2. Stormwater harvesting, water reuse, water conservation, and seawater desalination
3. Clean water and lower bill. When water is stored at a treatment plant the more water there is the better treatment it gets. This is because when there's less water the chemicals used to treat it may still have a taste left over. Overall, saving water will also lower your bill because that means you can spend less to save more money if you let water collect up.

PLEASE HELP!!! (ANSWER APPROPRIATELY)
Answer:
With the boost in warmer weather and excess water, populations will boom
Explanation:
Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.

The surface area/volume ratio is an important factor for one celled organisms. As a cell's volume grows, its surface area/volume ratio ______________, making it more difficult to acquire enough nutrients via diffusion. Question 7 options: increases freezes decreases stays the same
Answer: decreases
Explanation:
The surface area to the volume ratio will decrease as the volume of the cell increases or the cell gets larger. Therefore, if the volume of the cell increases beyond the certain limit the cell will not be able to imbibe nutrients as not enough material can pass through the cell membrane to accommodate the increase in volume of the cell.
