How do Euglena and sperm cells use flagella?

Answers

As Following:

Euglena move by a flagella , which is a elongated whip-like network that functions like a little engine. The flagella is located on the front part , and twirls in such a way as to drag the cell through the water. It is connected at an inward pocket called the pool.In sperm cells its help in movement.

What is purpose of flagella in eukaryotic cell?

Flagella in eukaryotes are used not only for Locomotion, but also for helping in phagocytosis and eukaryotic reproduction.

Thus, this is how Euglena and sperm cells use flagella.

Answer: founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony. The new population may be very different from the original population, both in terms of its genotypes and phenotypes.

Explanation:

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?

Answers

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​

Answers

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.

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.

Answers

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.

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.

Answers

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.
