Biology
2 answers:
zlopas [31]3 years ago
7 0
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Or


Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Answer:

chromosomes of a cell are in the cell nucleus. They carry the genetic information. Chromosomes are made up of DNA and protein combined as chromatin. Each chromosome contains many genes. Chromosomes come in pairs: one set from the mother; the other set from the father.

7 ways that invasive species affect the environment
seropon [69]

Invasive species reduce biodiversity levels, create a nuisance, cause economic loss, and disrupt ecosystem equilibrium.

<h3>Effects of invasive species</h3>
  • Invasive species tend to drive away or kill native species.
  • Invasive species reduce the overall biodiversity of plants or animals in the ecosystem.
  • They cause economic loss through the loss of important native species.
  • They create nuisance in the environment and may be costly to get rid of.
  • They affect ecosystem equilibrium by causing species change.
  • They are usually difficult to manage.

This structure encapsulates the pituitary gland to aid in protection and diffusion of releasing hormones from the anterior pituitar is Sella Turcica.

Sella Turcica it is very important during embryological development , mainly help in migration of Neural crest cell to frontonasal . This neural crest help in development of teeth and  Sella Turcica

What is Neural crest cell ?

  • A multipotent and migrating cell population called neural crest cells (NCCs) helps the developing embryo generate a variety of tissues. A group of disorders and illnesses called as neurocristopathies are caused by flaws in the growth, differentiation, and migration of NCCs.
  • Found in ectoderm in the margin of the neural tube
  • Contribute in the formation of a plethora of different tissues and organs
  • Its includes melanocytes, bone of smooth muscle

In 1883, Theodor Engelmann devised an experiment to find out which wavelengths of light were most used by photosynthetic organis
wel

Answer:

Oxygen loving bacteria are accumulated only in two areas in the slide, at its ends, areas rich in oxygen

Explanation:

A prism decomposed the light in different wavelengths between 400 and 700 nm.  Plants only absorbed some wavelenghts, one that peaks at about 440nm and the other around the 660 nm, as their particular Chlorophyls used to work.

Electrons from a reaction center from a photosystem (PSII) containing a particular chlorophyl , are launched to higher levels of energy when this is excited by light wavelength (680 nm) and travel by a molecular chain to an acceptor of electrons, forming ATP.  To refill the electrons in the reaction center, H2O is hydrolyzed, and their e- reach the reaction center.  In this step O2 is also produced.

A second photosystem (PSI) is also excited from another similar reaction center, whose electrons are used to produce reducing power in the form of NADPH.  This photosystem I also acts as acceptor of the electrons coming from PSII
