Answer:

Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.

Answer:

Explanation:

A seed is a plant embryo wrapped in a protective covering. A fruit is the ripened ovary of a plant which contains one or more seeds.

Most plants are rooted in place, which makes dispersing their fruits and seeds particularly important. Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.

Examples of the some common types of dispersal follow.

Wind

<-- Left : These seeds are transported by air currents. Small fruit or seeds with fine fluff can be carried high up into the air. Herbaceous plants of open areas (like dandelions, cattails, and milkweeds) often have this adaptation. Their seeds float up over neighboring plants even if the parent is growing low to the ground.

Right -->: The fruit of maple trees are also adapted to catch the wind. Many trees (like ashes and sweetgums) have winged fruits or seeds which drop from the tree and are caught by the wind as they fall.

Water

<-- Left : Sea bean seeds are adapted for dispersal by ocean currents. Sea bean vines grow along rivers and coasts. When the pods ripen, they split open and the seeds drop into the water. The beans have a thick seed coat to keep the salt-water out, and have internal structures which make them buoyant enough to float. They can drift for hundreds of miles before washing up onto land.

Coconuts (which are single-seeded fruits) are also adapted for water dispersal. Like sea beans, they have a thick shell to prevent the salt-water from damaging the seed, and the buoyant hull keeps the nut floating.

Animals: internal transport

<-- Left : Brightly colored fruits advertise for dispersers. They are highly visible to birds, promising a nutritious (and often sugary) reward. The seeds are tough and usually undamaged when eaten. They are dispersed when the bird makes a rest stop.

Right -->: Immature seeds in unripe fruit would die if eaten. The green of young fruit hides them among leaves. Unripe fruit are sour or bitter to discourage animals that do find them. Green fruit cling tightly to the plant, making it hard for animals to remove them.

Animals: external transport

<-- Left: Cockle burrs are dry fruit adapted for animal dispersal. The hooked spines catch on the hair (or socks) of passing animals. Dispersal is complete when the animal picks off the offending burr, hopefully dropping it in a new location suitable for growth.

Right -->: Fruit of the unicorn plant have an unusual adaptation for transport. As grazing deer or antelope walk over them, the spines catch around the animals' feet. When the animal finally gets annoyed and shakes the fruit off, dispersal is complete.

Answer:

i think it's meiosis identical but im not sure please tell me if it's right or not

Answer:

[tex]\boxed {\boxed {\sf Unique \ daughter \ cells}}[/tex]

Explanation:

There are two main types of cell division: mitosis and meiosis. Mitosis makes identical cells for growth and repair.

On the other hand, meiosis is used for sexual reproduction.

In this reproduction, one diploid cell produces 4 haploid gametes/sex cells, meaning they have half of the genetic information. This is so during fertilization, when a sperm and egg combine, the zygote will have a full set of chromosomes.

One of the most important parts of meiosis is called crossing over. In this step, the chromosomes exchange information and create totally unique chromosomes.

This is one reason why siblings, aside from identical twins, can look similar, but not identical!

Answer:

C. cytokinesis has formed two new cells.

Explanation:

Cell cycle has different stages called G1, S, G2, and M. ... This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.

Answer:

What are some of the types of human carbon emissions?

Carbon sources include the combustion of fossil fuels (coal, natural gas, and oil) by humans for energy and transportation and farmland (by animal respiration), although there are proposals for improvements in farming practices to reverse this.

Explanation:

The long term carbon sources are plants while a type of human carbon emissions fossil fuel burning.

The long term carbon sources includes, plants, oceans and other geological forms of carbon that are increasing via sequestration.

The carbon emission occur when carbon sources are burnt such fossil fuels, Jungle fire, and respiration of animals.

Therefore, the long term carbon sources are plants while a type of human carbon emissions fossil fuel burning.

Explanation:

when did sexual reproduction have that but anyway its A

Answer:

it is option B this is correct

Hydrophobic lipid fatty acid tails turn away that is they repel from water as lipids are fat insoluble which are present in cell membrane. Thus, the correct option is B.

Lipid molecules are hydrophobic in nature. There are three major classes of membrane lipid molecules including phospholipids, cholesterol, and glycolipids. The lipid composition of the inner and the outer monolayers are different from each other, this reflect different functions of the two faces of the cell membrane.

The most important lipid component of the plasma membrane is Fatty acid. An fatty acid is a monocarboxylic acid with a long generally 14 to 24 carbons long chain, it is unbranched, hydrophobic tail which may be either saturated or unsaturated with zero to six cis, non-conjugated double bonds in the compound. The hydrophobic lipid fatty acid tails turn away or repel from water.

Therefore, the correct option is B.

Answer:

Any sort of sexural reproduction.

Explanation:

Unlike asexual reproduction, sexual reproduction allows the species being produced to adapt the the changing environment around it to increase the chances of survival. For asexual reproduction, clones are made of the parent and, therefore, cannot withstand any extreme conditions that the parent species couldn't. For a changing environment, sexual is the best to allow the specimen and its offspring to change positively along with the environment.

Have a supercalifragilisticexpialidocious day!

Answer:

When humans reproduce, there are two parents involved. DNA must be passed from both the mother and father to the child. Humans cannot reproduce with just one parent; humans can only reproduce sexually. But having just one parent is possible in other eukaryotic organisms, including some insects, fish, and reptiles. These organisms can reproduce asexually, meaning the offspring ("children") have a single parent and share the exact same genetic material as the parent. This is very different from reproduction in humans. Bacteria, being a prokaryotic, single-celled organism, must reproduce asexually.

Answer:

Plate tectonics

Explanation:

Plate tectonics explains the features and movement of earth surface in the present and the past.

These plates are pieces of cracked shell that rest on the hot , molten rock of earth's mantle. The heat from the radioactive processes within the planet's inferior causes the plates to move, sometimes towards and sometimes away from each other.

These rocks collected were as a result of plate tectonics which drifted away.

Answer:

Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
