Answer:

The first, which was published in 2014 and included the review of 147 studies, concluded that GM crops have allowed an average increase in agricultural yield by 22 percent and increased farmers' profits by 68 percent, with profit margins even larger in developing countries.Explanation:

the rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)?
Oduvanchick [21]

The rapid depolarization phase of the action potentials of myocardial contractile cells is due to Na⁺ ion.

The depolarization is caused when Na⁺ ions rapidly enters into neuron through open sodium channels. Sodium ions plays important role in various physiological process such as regulating blood volume, ph regulation,  maintaining blood pressure, energy metabolism,osmotic equilibrium, excitation-contraction coupling, maintenance of cellular homeostasis, development and growth.

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same featu
Liono4ka [1.6K]

Answer:

If the two organisms are heterozygous for the dominant trait.

Explanation:

For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.

According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.

When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.

Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.

mixas84 [53]

Proteins are important biomolecules. Proteins are synthesized and often packaged for secretion into other cells within an organism. A variety of organelles play a role in producing, packaging, and moving proteins.

Organelles of Eukaryotic Cells

Organelle Function

Nucleus The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.

Mitochondria Make energy out of food

Ribosomes Make protein

Golgi Apparatus Make, process and package proteins

SOMEBODY PLEASE HELP ME ITS URGENT I NEED A PARAGRAPH THIS IS THE ONLY THING THEY GAVE ME WILL MARK BRAINLIEST​
AfilCa [17]

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.
