Della and Nick drove at constant
speed from town A to town B along
the same road. The distance between the
two towns was 210 km. Nick left
Town A half an hour later than Della
Both of them arrived in Town B at
the same time . Della drove at a
Speed of 60 km/h Find Nick's speed.
Plzz help mee
Answer:
70 km/hr
Explanation:
Distance between town A and B = 210 km
Della's speed = 60 km/hr
Time taken by Della = distance / speed
Time taken by Della = 210 km / 60km/ hr
Time taken by Della = 3.5 hours
Since Nick left half an hour later Than Della ;
Then, Nick's travel time = 3.5 - 0.5 = 3 hours
Nick's average speed = Distance /time
Nick's average speed = 210 / 3 = 70km/hr

What kind of an animal do you think this is? Explain why:
Answer:
I beleive its somthing close to a pig
Explanation:
The DNA sequence is closest to the pig . The amino acids Gly, Thr, Leu, and Ala are from the "unknown animal." On the worksheet, the pigs amino acids are Gly, Thr, Phe, and Ala. There is only one different amino acid between the two.

What is the general relationship between distance from the sun and a planets density?
Answer:
There is no connection between a planet's distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period). While it is true that, generally speaking, the gas giants have higher rotation rates than the earth like planets closer to the Sun, any correlation is only coincidental.

What significance does density have for earth?
Answer:
The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
In the glycolytic pathway, the enzyme triose phosphate isomerase catalyzes the production of glyceraldehyde 3-phosphate (GAP) from dihydroxyacetone phosphate (DHAP). GAP continues through glycolysis via the reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase. In a muscle (myocyte) cell culture model, anaerobic conditions lead to cell death when triose phosphate isomerase is inhibited. In this same model, cells with inhibited triose phosphate isomerase survive under aerobic conditions. Briefly explain these findings including a discussion of energy production in anaerobic versus aerobic metabolism.
Answer:
In an anaerobic environment, organisms convert glucose into ethanol or lactate. In this condition, glycolysis generates 2 molecules of ATP and one molecule of NADH with the pyruvate. NADH molecule supports glycolysis by oxidized to NAD+ during the fermentation process.
Here one 6-C molecule breaks into two molecules G3P and DHAP, TPI or triose phosphate isomerase interconvert these two isomers and each triose is responsible for the production of two ATP molecules but if TPI is inhibited then there will be one ATP production which is not enough for supporting cellular process under the absence of oxygen and cell do not survive.
But in aerobic conditions pyruvate converted to acetyl CoA which produces 3 NADH, 1 FADH2, and 1 ATP that will get enough ATP by the oxidative phosphorylation hence will survive even if TPI is inhibited.

Many plants produce seeds which have small hooks on them. These hooks will attach to animals as they
move past the plants. What process do these hooks help the plant with?
A. pollination
B. fertilization
C. germination
D. seed dispersal
Answer:
A. Pollination
Explanation:
Because the "Hook" is helping the "Seed" get to other places to grow.
the number of molecules of ATP produced from one molecule of glucose through glycolysis/oxidative phosphorylation is respectively
Answer:
Glycolysis is the answer
Answer:
Explanation:
Glycolysis starts with one molecule of glucose and ends with two pyruvate which is pyruvic acid. molecules and a total of four ATP molecules, and two molecules of NADH.
While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

Answer: gender schema theory
Explanation:
Suggest that children are active learners who essentially socialize themselves by Gender schema theory.
What do you mean by Gender schema theory?Gender schema theory may be defined as a concept that children understand regarding male and female positions and roles from the culture in which they live.
Gender schema theory deals with the principle of socialization among young children. It is the basis of learning the concept and functions associated with societies.

An ecologist is studying a newly discovered animal. The ecologist finds that it reproduces quickly and has many offspring each time it reproduces.
Which type of organism is it?
A. logistical
B. an r-strategist
C. a K-strategist
D. density dependent
THE ANSWER IS....
Answer:
B. an r-strategist
Explanation:
R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size, 5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.
Answer:
Thanks so much for giving the answer!
It is r-stragery though.
k-stratergy produce fewer offspring slowly- such as an elephant.
r-strategey produce offsping rapidly- such as a (nasty) fly.

Quick question. I am trying to cite my sources for my biology research project and the website that I used is a rare disease informational center with different topics. For example there is a summary section, a symptoms section etc.... I need to cite my sources however each section has a different publication date because they don’t update the entire article at once. I am currently trying to use an in text citation for the summary because I used a quote from the summary so do I just use the summary publication? But I did use other sections of this website for other parts of my essay so when it comes time to making my bibliography what do I do
Answer:
For your bibliography, you need to put the website but also put the sections you got your examples from. Also, don't forget to put the person who published the summary down as well. Hope this helped
