A cluster of tumor cells that produces and secretes growth factors to induce surrounding cells to grow and divide is showing paracrine type of cell-to-cell signaling.

<h3>Paracrine signalling : </h3>

it is a type of the cell signaling.

it ptomotes cellular communication in which a cell produce a signal to induce change in the nearby cells.also altering the behavior of these cells.

Example neurotransmitters.

<h3>What is cell signaling? </h3>

It is type of signaling process through which one cell can communicate with another cell.

It can be intercellular or intracellular.

Cell signalling molecules are of 5 types: they are

Intracrine signaling, Autocrine signaling, Juxtacrine signaling, Paracrine signaling ,Endocrine signaling

it involves both mechanical and biochemical pathway for signaling.

cell signaling strats at the binding of signal molecules to the receptors, then signal transduction where chemical signal activates the enzyme and final step is the collection of response.

During meiosis I, ____________ chromosomes line up side by side and may shuffle genetic material between themselves.
lozanna [386]

During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.

<h3>What is Meiosis?</h3>
  • In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
  • Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
  • Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
  • It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
  • By halving the same, it keeps the chromosomal count constant.
<h3>What is chromosome?</h3>
  • A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
  • Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

It can be seen on a cladogram that modern birds and reptiles share a common ancestor. Select the piece of evidence that best sup
garri49 [273]

The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.

In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.

The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.

These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.
