Answer: The remains of an organism that lived 500 years ago is called a fossil.
Explanation:
A fossil can be defined as dead remains of plants and animals that existed past geological era. The traces of bones, and other skeletal remains, pollen, hard wooden materials can be found in the compact rock as the soft parts of the organisms are decomposed and decayed. The remains like shells, exoskeleton, amber, hair, and other can also be found. It takes many years for the development of fossil beneath the earth crust. The morphological, anatomical, physiological and molecular features can be assessed to know the age of the fossil.
Answer:
fossil is any trace of prehistoric life
You are studying a population of sexual, diploid insects. One particular trait, wing size, is controlled by a single locus with two alleles. The allele for narrow wing size is dominant (N) and the allele for wide wing size is recessive (n). The population you are studying is comprised of 97 individuals with the NN genotype, 52 individuals with the Nn genotype and 50 individuals with the nn genotype. What is expected frequency of the dominant allele (A1) after selection
Answer:
The expected frequency of the dominant allele, N is 0.70
Explanation:
Total number of individuals in the insect population = 97 + 52 + 50 = 199
From Hardy-Weinberg equation, p2 + 2pq + q2 = 1; also p + q = 1
The frequency of dominant allele, N = p
Frequency of dominant NN genotype individuals = p2
From the given data: the population is comprised of 97 individuals with the NN genotype, 52 individuals with the Nn genotype and 50 individuals with the nn genotype.
Frequency of NN genotype individuals p2 = number of individuals with NN genotype ÷ total insect population
p2 = 97/ 199
p2 = 0.487
p = 0.697 = 0.70
Therefore, the expected frequency of the dominant allele, N is equal to 0.70

Avanti works in a bookstore. She has four books and is going to place them in two stacks. The diagram above shows the books before they touch. Use the information in the diagram to answer the question. How did the temperatures of the four books compare before they touched? How will the temperatures of the two top books compare after the books have been touching for a while, and why? HELP
Answer:
Well they didn't transfer any energy when they weren’t touching and it didn't produce any energy if it didn’t move. Since they are on top of each other they are causing momentum on each other creating kinetic energy

20. Some urea diffuses out of the collecting duct, because the tubule is permeable to urea. This adaptation allows the interstitial fluid of the inner kidney to become more concentrated than the filtrate. In turn, more water is reabsorbed by blood. What a perfect system! The filtrate reaching the collecting duct is called urine. Is urine more or less concentrated than the initial filtrate
Answer:
Urine is more concentrated than initial filtrate. Urine is, in fact, four times more concentrated than initial filtrate.
Explanation:
The urinary system is the one in charge of filtrate blood and propduce urine. The main stars in the system are kidneys and the functional unit of them are the nephrons.
There are many steps in producing urine. Fluid goes between different parts of the kidney: renal tubule, renal corpuscle, bowman's capsule, etc. We have through all these parts these following steps: filtration, reabsorption to blood, secretion from blood and excretion.
From filtrate, the boody reabsorbs sodium chloride, glucose, water and amino acids. When the fluids moves down the loop of Henle, it becomes less concentrated, so it is full of water. At the end, urine is four times more concentrated than initial filtrate.
A man has type A blood and his wife has type B blood. A physician types the blood of their four children and
finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens.

how to calculate the first hundred terms of a sequence
Answer:
Question: what is the sum of the first 100 whole numbers?? how am i supposed to work this out efficiently? thanks
The question you asked relates back to a famous mathematician, Gauss. In elementary school in the late 1700’s, Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher, but Gauss found the answer rather quickly by discovering a pattern. His observation was as follows:
1 + 2 + 3 + 4 + … + 98 + 99 + 100
Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.
1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50
100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51
1 + 100 = 101
2 + 99 = 101
3 + 98 = 101
.
.
.
48 + 53 = 101
49 + 52 = 101
50 + 51 = 101
Gauss realized then that his final total would be 50(101) = 5050.
The sequence of numbers (1, 2, 3, … , 100) is arithmetic and when we are looking for the sum of a sequence, we call it a series. Thanks to Gauss, there is a special formula we can use to find the sum of a series:
S is the sum of the series and n is the number of terms in the series, in this case, 100.

ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H ) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis. Two types of processes that contribute to the formation of the proton gradient are: processes that release H from compounds that contain hydrogen, and processes that transport H across the thylakoid membrane.
Complete question:
ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H+) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis.
Two types of processes that contribute to the formation of the proton gradient are:
processes that release H+ from compounds that contain hydrogen, and
processes that transport H+ across the thylakoid membrane.
Drag the labels to the appropriate locations on the diagram of the thylakoid membrane. Use only the blue labels for the blue targets, and only the pink labels for the pink targets.
Note: One blue target and one pink target should be left empty.

Answer:
You will find the image and the answer in the attached files
Explanation:
Fosforilation of ADP to ATP occurs while electrons descend through the electron chain, from photosystem II to photosystem I.
Placed in the thylakoid membrane, there are molecules and complexes that participate in light-dependent reactions. The places that occupy these molecules in the membrane make possible ATP synthesis. Protons are released into the thylakoid space when the water molecules split in photosystem II. Membranes are impermeable to protons, so they can not leave the thylakoid space, nor enter without a protein transporter. Through the membrane, there is an electrochemical gradient as additional protons are pumped from the stroma to the thylakoid space, using the released energy as electrons move along the chain. ADP phosphorylates to ATP while protons move from the thylakoid space to the stroma in favor of the electrochemical gradient, through ATP synthase. ATP synthesis occurs in the stroma.

3. What can the reader reasonably conclude based on the information in this passage?
A. Animals in the rain forest are strictly independent of each other.
B. Animals in the rain forest have found ways to thwart their competition and survive
C. All animals in the rain forest have the same adaptations.
D. Animals in the rain forest all need the same amount of sunlight.
i think answer is D animal in the rain forest
All animals in the rainforest have the same adaptations. Therefore, option C is correct.
What is adaptation?A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a person does or has on them that makes it easier for them to locate food, water, mates, and shelter. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this.
Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their colour to blend in. Predators find it challenging to locate them in search of food as a result. Hence, option C is correct.

A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
is compressed to a volume of 4.1 L. What would be the new
pressure?
Answer:
Final pressure, P2 = 362.26 kPa
Explanation:
Given the following data;
Initial volume = 32.5 Liters
Initial pressure = 45.7 kPa
Final volume = 4.1 Liters
To find the final pressure, we would use Boyle's law;
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Substituting into the equation, we have;
[tex] 45.7 * 32.5 = P_{2} * 4.1 [/tex]
[tex] 1485.25 = 4.1P_{2} [/tex]
[tex] P_{2} = \frac {1485.25}{4.1}[/tex]
[tex] P_{2} = 362.26 [/tex]
Final pressure, P2 = 362.26 kPa
