Answer:
" Fossil record" is the right answer.

Prior knowledge, comprising fossils, rests as well as impressions of species perfectly deposited throughout sedimentary rock throughout early archaeological eras.These are established upon this superpose law which always claims that perhaps the lower layers typically younger than the whole upper ones in uninterrupted factors leading.PLEASE HELP ME WITH THIS BIO QUESTION!
Answer:
Option 1: XnY
Explanation:
X-linked recessive traits can occur in both males and females. Since its recessive it needs both XnXn in females to show up but for males who are hemizygous (XY) they only need a defective copy of Xn for the disease to show up thus option 1 is correct.
I have added a helpful illustration below where we are talking about another x-linked recessive condition in humans: hemophilia.

6 reasons why Meiosis and mitosis are different (PLEASE HELP)
Answer:
Reasons why they're different :
Explanation:
1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).
2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.
3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.
4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.
5. Unlike mitosis, meiosis differs in males and females.
6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.

❀ The word “photosynthesis” is derîved from the Greek words "phos" (which means “light”) and "σύνθ-εóîς" (which means “combining together.”) And so it means “combining together with the help of light.”
❀ The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.
❀ Following is the photosynthesis formula:

Mold is made up of many fungi cells. Mold would be considered what type of organism?
A. unicellular
B. prokaryotic
C. multicellular
Answer:
The answer is Multicellular
Mold would be considered a multicellular organism, which is made up of many fungi cells.
When it is said that living beings are made up of cells, what is meant is, if they are multicellular organisms.
Eukaryotes include all members of the animal and plant kingdoms, including fungi, which exist both in multicellular forms (molds) and in unicellular forms (yeasts), and protozoa, which are exclusively single-celled.
About multicellular organism molds:
The filaments that make up the mycelium are called hyphae. The hyphae may be separated into generally multinucleated sections by means of perforated septa, or may be absent.The cell wall of the mycelium of molds resembles an extensive tubular system through which the cytoplasm advances to disperse and search for nutrients.Therefore, we can conclude that mold would be considered a multicellular organism, which is made up of many fungi cells.

Use the following information to answer the questions below. Skin color in a certain species of fish is inherited via a single gene with four different alleles. One fish of this type has alleles 1 and 3 (S1S3) and its mate has alleles 2 and 4 (S2S4). If each allele confers a unit of color darkness such that S1 has one unit, S2 has two units, and so on, then what proportion of their offspring would be expected to have five units of color
Answer:
1/2 = 50% of the progeny is expected to have 5 units of color → S1S4 + S2S3
Explanation:
Available data:
Single gene with four different alleles → S1, S2, S3, S4Each allele confers a unit of color darknessS1 one unitS2 two unitsS3 three unitsS4 four unitsCross:
Parentals) S1S3 x S2S4
Gametes) S1 S3 S2 S4
F1) 1/4 = 25% of the progeny is expected to be S1S2 → 3 units
1/4 = 25% of the progeny is expected to be S1S4 → 5 units
1/4 = 25% of the progeny is expected to be S2S3 → 5 units
1/4 = 25% of the progeny is expected to be S3S4 → 7 units
1/2 = 50% of the progeny is expected to have 5 units of color → 1/4 = 25% S1S4 + 1/4 = 25% S2S3

Describe the connection between the digestive and circulatory systems (in detail)
Answer:
Explanation:(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).
Which statement accurately describes radioactive dating?
Explanation:
Radioactive dating works on the principle that a radioactive isotope can decay into the stable daughter nuclei at a constant rate. Geologist generally use the principle for half life. Half life is the time required for half of the radioactive substance to decay. This is constant for a particular element.

Which factor does NOT provide evidence of common ancestry?
a.) DNA
b.) organism size
c.) stages of early development
d.) homologous structures
The size of the organism does not provide any evidence of common ancestry. So, the correct option is B.
What do you mean by Common ancestors?Common ancestors may be defined as those characteristics of different organisms that have two or more descendants in common.
The nature and morphology of the DNA, stages, and properties of the early development of organisms, and homologous structures provide significant evidence of common ancestry between the organisms of different species.
Therefore, the correct option for this question is B.

Which technological tool helps earth scientists gain new knowledge about earth’s subsurface?
Group of answer choices.
A. Global positioning system
B. Digital balance
C. Ground penetrating radar
G. Hydrometer
Answer:
ground penetrating radar
Ground penetrating radar technological tool helps earth scientists gain new knowledge about earth’s subsurface. Thus the correct option is C.
What is Ground penetrating radar?Ground penetrating radar detects non-metal and metal objects, as well as voids and underground irregularities. It makes possible to measure the depth, dimensions, thickness of targets. It provides data quickly and can cover a large site area.
Ground penetrating radar can go deep up to 100 feet (30 meters) in low conductivity materials such as dry sand or granite. Moist shale, clays, and other high conductivity materials, may attenuate or absorb GPR signals, greatly decreasing the depth of penetration to 3 feet (1 meter) or less.

Assuming these are carbon dioxide molecules, which way do you think the molecules will move and why?
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
B. Into the cell. They want to move from low to high concentration (UP the concentration gradient).
Answer:
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
Explanation:
Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).
Answer:
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
Explanation:
The option (A) is the correct answer. This statement is the required answer.
Si contamos con mas tecnologia ahora,por que creen que no es posible regresar de Marte si lo es regresar de la Luna
Answer:
Debido a la gravedad.
Explicación:
No es posible regresar de Marte si es posible regresar de la Luna porque la masa es un planeta que tiene una alta fuerza de atracción gravitacional en comparación con la luna que tiene una fuerza gravitacional muy baja. La luna es una estrella que tiene una fuerza gravitacional baja mientras que, por otro lado, Marte es un planeta y más grande que la luna, por lo que tiene más fuerza de atracción gravitacional en comparación con la luna y esa es la razón por la que no podemos regresar de la luna fácilmente desde el Marte en comparación con la luna.
