is gene paired on endosperm cell?​

Answers

Answer 1

Answer:

yes

Explanation:

What is the genetic makeup of endosperm?

One sperm fuses with the egg to form a diploid zygote, and the other sperm fuses with two female-gametophyte nuclei (known as polar nuclei) to form the triploid primary-endosperm nucleus. Therefore, the endosperm, which devel- ops from this triploid nucleus, has an unusual genetic composition

how has the change in the human population over time affected the environment

Answers

Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.
One way the increase in human population has affected the environment over time is that the amount of CO2 in the atmosphere has greatly increased. Humans manufacture a lot of product, and humans burning all the fossil fuels needed to create these items has released a ton more CO2 into the environment than is natural for the environment.

briefly describe the nebula theory formation of our solar system use the words protostar and protoplanets in your discussion

Answers

Answer:

Below!

Explanation:

Currently the best theory is the Nebular Theory. This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova. The nebula started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a Protostar.

A protostar is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A protostar becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.

Three processes occurred with the nebular collapse:

Temperatures continued to increase The solar nebula spun faster and faster The solar nebula disk flattened

The orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

What is Transpiration ???!​

Answers

[tex]\huge \bf༆ Answer ༄[/tex]

Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.

Two main functions of transpiration ~

It causes transpirational pull that helps in transportation of water from roots to upper portions of the plant

It helps to release excess water
Answer -:

Plant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .

Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated process

Types of Transpiration -:

1 Stomatal Transpiration ;

it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.

2 Cuticular Transpiration;

it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.

3 Lenticular Transpiration

it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.
