can someone give me good evidence please i will give you brainliest

Answers

Answer:

you can get evidence by observing how people have different traits from their parents, like one sibling can look different than they other sibling, they can get traits from older generations, like you can have a family that has black hair or dark brown and one of their kids got light brown hair because that was passed down or skipped through a generation.

The oxygen released during photosynthesis comes from molecules of water
True or False

Answers

Answer: False

Photolysis takes place in the light dependent reaction of the photosynthesis. The reaction can be represented as:  H 2 O + 2 photons --> 2 e  −   + 2H  +   + O.  Here, the electrons released are accepted by the photosystem to fulfill the electron gap. The last electron acceptor is the oxygen and thus, the oxygen is liberated from the water molecule. The experiments conducted by Samuel Ruben and Martin Kamen by using radioactive isotopes helped to prove that the oxygen liberated during photosynthesis came from photolysis the water.

Explanation:

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.Carbon dioxide is released during photosynthesis. Plants which synthesise their food themselves are called saprotrophs.

Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?

a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose

Answers

Answer:

a. analogous

b. homologous

c. analogous

d. homologous  

e. homologous

f. homologous  

Explanation:

a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.

b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.

c. Analogous. These structures evolved independently through convergent evolution in both groups.

d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).

e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).

f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).

In pea plants, height is determined by an allele for tallness (T) that is dominant over an allele for shortness (t). What is the probability that a gamete, selected at random, would carry the short allele (t) in a cross of heterozygous tall pea plants?

A. 1/8
B. 1/4
C. 1/2
D. 3/4

Answers

Answer:

C. 1/2

Explanation:

I took the test and got it right.

Heterozygous organisms show presence of two alternatives alleles for same trait. For plant height, a heterozygous tall plant, will show both the T (for tallness) and t (for shortness) alleles, as T allele is dominant over t allele. When a cross is made between heterozygous tall plants (Tt), there are 50% chances that a randomly selected allele will carry allele for shortness (t) as shown below:
Thus, "the probability that a randomly selected gamete will carry 't' allele in a cross between heterozygous tall pea plants, is 1/2."

Which location has the warmer air temperature: Tarapoto or Neuquén? Why?
view the pic below.​

Answers

Answer:

Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature.Neuquén, because more energy is transferred from the sun directly to the air. Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.

Answer:

The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.

And that is why the neuquen has the warmer air temperature!

Answers

Answer:

- In water, phospholipids spontaneously arrange into a bilayer

- Steroids in cell membranes allow the membrane to be more fluid

- Phospholipid bilayers surround all eukaryotic cells

- Both plant and animal cell membranes are considered fluid mosaics

Explanation:

All living things (i.e.. both eukaryotic and eukaryotic organisms) are composed of cells, and all cells have cell membranes. In an aqueous environment, phospholipids spontaneously form bilayers: hydrophilic heads of phospholipids face the water environment at the surface of the bilayer, while hydrophobic fatty acid chains are shielded from the water in the interior. Steroids are lipids that intercalate into the bilayer of the cell plasma membrane, reducing the fluidity of the membrane. Integral membrane proteins may have different biological roles. For example, permeases are integral membrane proteins that facilitate the diffusion of certain molecules (e.g., glucose) across the cell membrane by passive transport. Both plant and animal cell membranes are considered fluid mosaics where different types of molecules (e.g., phospholipids, cholesterol, proteins, etc) are constantly moving across the membrane.

TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.
