Answer:
Asexual (vegetative) reproduction
Explanation:
Asexual reproduction is a type of reproduction that involves only a single parent. As opposed to sexual reproduction, it does not involve the formation of sex cells or gametes.
According to this question, Bryophyllum, which is a plant known to propagate itself via its leaves is practicing a form of asexual reproduction called VEGETATIVE PROPAGATION, which is the propagation of a plant via its vegetative parts e.g. stems, leaves, cuttings etc.

Persistence length for a cytoskeletal filament is the minimum filament length at which random thermal fluctuations are likely to cause it to bend. Which of the following comparisons are true, considering the persistence lengths of (a) an actin filament, (b) a bundle of cross-linked actin filaments, and (c) a microtubule
The provided question is incomplete as the group of choices were not given, however, the choices as follows:
A. (a > b) and (a > c)
B. (a > b) and (a < c)
C. (a < b) and (a > c)
D. (a < b) and (a < c)
E. (a > b) and (b > c)
Answer:
The correct answer is - D. (a < b) and (a < c)
Explanation:
The persistent length of actin filaments, a bundle of cross-linked actin filaments and microtubules can be compared on their typical persistent length.
The persistent length of actin filaments is 15 µm. And due to the crosslink with one another to make a bundle their length reduced As the actin filaments cross-link each other their persistent length will be reduced. however, it is still longer than single actin filament around 20 nm.
The persistent length of microtubules is 6mm.
So b > a, a < b and a < c.
So fourth option a < c and b > a is the correct answer.

George and Kyle were taking a quiz. This was item four:
Scientists just discovered a new kind of organism and gave it the common name blue spinner. Make one statement that must be true about the structure of a blue spinner.
George wrote, "A blue spinner is made of at least one cell."
Kyle wrote, "A blue spinner has tissues that perform specific functions."
Which of the responses is correct? Explain the error made in the incorrect response.
Answer:
George Is correct.
A blue spinner is made up of at least one cell.
Explanation:
George and Kyle took the quiz about the new kind of organism. The characteristics of this organism is not known as it has just discovered. George statement can be true about blue spinner as all living organism are made up of at least one cell. The blue spinner can be unicellular or multicellular organism which will be discovered later by scientists.
An individual way of life can be either unicellular or multicellular is called an organisms. It is a single entity that functions to live and survive.
The statement made by George is correct.
According to George blue spinner is made up of at least one cell. For an organism to be living it has to be composed of either one cell or multiple cells.As the new species discovered can be either multicellular or unicellular.Kyle's statement is incorrect as it is known whether the organism is a single or multi-celled structure as the deduction about tissues cannot be made.Therefore, George is correct and Kyle's is incorrect.

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).
Corn heterozygous for kernel color and kernel texture are interbred resulting in the following offspring.
330 red smooth
97 red wrinkled
101 yellow smooth
32 yellow wrinkled
Perform a Contingency Chi-Square analysis and determine if kernel color is independent of kernel texture.
a. Show your DF, chi square value, and p value
b. Do you reject or fail to reject the null hypothesis?
c. Is kernel color independent of kernel texture?
Answer:
a. df = 3, chi-square = 1.7333, p value = 7.815
b. we fail to reject null hypothesis
c. it is independent of kernel texture
Explanation:
h0; there is independence
h1; no independence
9:3:3:1 this is the phenotypic ratio
9+3+3+1 = 16
330 red smooth + 97 red wrinkled + 101 yellow smooth + 32 yellow wrinkled
total observed = 560
1. the degree of freedom = n-1
n =4, 4-1 = 3
to get the chi square computation
(O-E)²/E
expected value for red smooth,
9/16 x 560 = 315
chisquare = (330-315)²/315 = 0.7143
expected for red wrinkled
3/16*560 = 105
chisquare = (97-105)²/105 = 0.6095
expected for yellow smooth
3/16*560 = 105
chisquare = (101-105)²/105 = 0.1524
expected for yelow wrinkled
1/16 * 560 = 35
chisquare = (32-35)²/35 = 0.2571
total chisquare = 0.7143+0.6095+0.1524+0.2571
= 1.7333
with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815
1.7333 < 7.815
so we fail to reject the null
c. we conclude that kernel color is independent of kernel texture

short note on occurrence of water in different source and state
Answer:
Water circulates in nature through a continuous and permanent process called the hydrological cycle or the water cycle. In this process the physical and biological elements of nature intervene, atmosphere, rain, water from lakes, rivers and seas, soil and vegetation. Water is in several states: solid state, which is ice. Liquid state, includes groundwater, which is found in the deep layers of the soil, and surface water, which includes innumerable rivers, and a gaseous state, which is found in air and clouds.
Explanation:
Water covers 71% of the earth's surface. The water cycle comprises three phases: Evaporation, filling the atmosphere with large amounts of water vapor (gaseous state). Condensation, forming water droplets in the form of a cloud or mist. Precipitation: the water vapor that is the clouds cools and precipitates in the form of rain, hail or snow. When the rain falls, some of the water is retained in the dense foliage and branches of the trees. Another seeps into the ground, forming the layers of underground water and the other part drains superficially forming streams, rivers or increasing their flow. All water, through evaporation, can change back to the gaseous state, restarting the water cycle. On our planet, water is located mainly in the oceans where 96.5% of total water is concentrated, glaciers and polar caps have 1.74%, underground deposits in (aquifers), and continental glaciers represent the 1.72% and the remaining 0.04% is distributed in decreasing order between lakes, soil moisture, atmosphere, reservoirs, rivers and living beings. Water is found in nature in three different forms or states in: solid state, such as ice, hail or snow, liquid state, such as the water we consume and the water of the seas, rivers and lakes and in the gaseous, when it forms clouds or steam that comes out of boiling water.

Daryl learns that millions of years ago, Earth's climate went through a
rapid change and experienced an ice age. This rapid climate change put a
lot of stress on the plant life of Earth. How would plant life most likely
react to this stress? *
Plants that adapted to the cooler conditions would survive and rapidly evolve into a
new species.
O All plant life would become extinct, and the new plants would evolve very slowly.
The plants would gradually change over time and produce new species.
All plants would evolve into new species and survive the climate change.
Answer:
Plants that adapted to the cooler conditions would survive and rapidly evolve into a new species.
Explanation:
The plants will react by evolving through natural selection.
The plant species that do not have the genes to adapt to the rapid change in climate would become extinct while those with adaptive genes will survive, reproduce, and contribute rapidly to the development of future generations.
In other words, natural selection selects for individuals with adaptive genes and ensures that such individuals reproduce more and give rise to future generations with the adaptive gene while individuals that are poorly adapted to the change in climate gradually fade off the population.
Hence, the plants that adapted to the cooler conditions would survive and rapidly evolve into new species.
